java.lan.OutOfMemoryError
Hi all,
When I run my webapp from localhost, everything seems to be fine. When I put
a link to in on my website and try running accessing it from there, I get:
2002-03-22 12:47:12 - Ctx( /RobertDouglass ): Exception in: R(
/RobertDouglass +
/img/Beetle8.jpg + null) - java.lang.OutOfMemoryError
and Tomcat eventually crashes, but not before my data is corrupted.
I also get the following error:
2002-03-20 22:27:01 - Ctx( /RobertDouglass ): IOException in: R(
/RobertDouglass
+ /img/Beetle6.jpg + null) Software caused connection abort: socket write
error
where do I start looking to fix this?
Thanks,
Robert Douglass

Sorry, I have to revise my earlier statement... I produced the same behavior
from localhost. That doesn't seem to have anything to do with it.
Eventually, the error buffer fills up so completely that it keeps scrolling
through them for a couple of seconds after I close Tomcat:
2002-03-22 13:05:09 - Ctx( /RobertDouglass ): IllegalStateException in: R(
/Robe
rtDouglass + /img/Beetle4.jpg + null) Current state = FLUSHED, new state =

Current state = FLUSHED, new state = CODING
+ 3,765 others!!!
I did think about modifying the TC code to bail the error handling process
in the event of the IllegalStateException, but then set a Junior Developer
to try other TC versions. His report is that this does not happen in 4.01.
We haven't rolled out the change for retesting yet, hence my interest in the
observation that it may occur in 4.03.
Think it's time I went home for the weekend!

RE: java.lan.OutOfMemoryError
Posted by Robert Douglass <r....@onlinehome.de>.
The problem occurs repeatedly. It handles light traffic alright, but as soon
as it has to handle more than one or two page requests per second, the error
log overflows. That is very likely why it is out of memory. When I shut
Tomcat down, the error log needs another MINUTE or two to display all of the
errors in the console window! There is, however, usually no discernable
problem in the application itself. From the client's point of view, it is
business as usual. You can see some code (and get some Duke Dollars) on the

Re: java.lan.OutOfMemoryError
Posted by David Hamilton <da...@financity.co.uk>.
No, AFAIK it is because the IOException is handled differently from the
IllegalStateException:
The IllegalStateException causes a recursive error handling trap to occur
that gradually fills up the stack and blows the system.
Because you've got a number of requests happening it hides the fact that
IllegalStateException is happening repeatedly off the handling of one
(closed) request. IMHO!

I changed the JDK back to 1.3.1 (which is what my class files were compiled
with) and the error message:
2002-03-22 22:17:32 - Ctx( /RobertDouglass ): IOException in: R( /Robert

is still there every time it loads an image, but I cannot get the
java.lang.OutOfMemoryError.
Whether this is because more resources are available on my system, I don't
know.

Re: java.lan.OutOfMemoryError
Posted by David Hamilton <da...@financity.co.uk>.
I know that IllegalStateException with TC 4.0x was reported on this list a
few weeks ago - but IIRC the evaluation of it indicated that it was due to
another reason than the one I described below (was it servlet forwarding, or
something like that?)
Is your similar problem occurring recursively, or just the once?

You sure?
I only ask because if you are I have to got back to my team member who
reported 4.01 fixed it and
get him to
a) double check with 4.01 and
b) find if 4.03 is different.

Coo - is your whole LAN out of memory? Wow! (Sorry couldn't resist.)
Seriously: You using JDK 1.4? We found that TC 3.2.3 with JDK 1.4 was
giving us a recursive IllegalStateException which locked up the server
and eventually fell over.
Reason: Any cancelled or closed HTTP request would apparently cause
this problem. Seems that this causes the output stream to be closed and
under JDK 1.4 any attempt to write to it causes an
IllegalStateException.
Closer investigation showed that the error handling in 3.2.3 was fairly
junky, (lots of empty exception handlers, hopefully addressed in 3.3/4.0
series) and it tries to handle by passing it to the error servlet, which
tries to write out the error, which gives an IllegalStateException,
which redirects to the error servlet, etc.
Solution: TC 4.01 does not exhibit this behaviour, so we upgraded.
Hope that helps

Hmmmm. I recant my heresy!
Tomcat is not to blame here. I have just reminded myself that IOException
is the only checked exception thrown by OutputStream and
IllegalStateException is unchecked. Given that the rule-of-thumb is 'use
unchecked exceptions only if the error cannot occur in a bug-free, correctly
running, well configured system', and that a closed socket can happen any
system, the JDK classes should be throwing IOException.

That was my evaluation. The error handling looked distinctly fragile to me.
To be honest, it looks like Sun have tightened up their state-checking with
the nio package (good) and exposed some weaknesses in the tomcat code (bad).
But then I have strong opinions on error handling (i.e. you should define a
policy for it in your coding standard). It seems too often that it's just
left to individual coders to make arbitrary decisions on which errors ignore

Tomcat bug, Java Bug, or neither?
Posted by Brandon Cruz <bc...@norvax.com>.
Using Tomcat 3.2.4, has anyone noticed an error if you attempt to use
<jsp:forward> to forward requests to a page that also uses a <jsp:forward>
tag? It seems that this never works and results in a 404 error. Is there
some spec that does not allow this, is it a tomcat bug, or is it just a java
bug? Is there a better way to accomplish this task other than using
javascript to redirect?
Tomcat 3.2.4
JDK 1.3.1_01

Jeff,
That's pretty harsh on Sun. How many major software vendors do you know
that get it completely right first time?
At least Sun have the decency to inform it's customers (many of whom use
their products for free) of what the current bugs are. And they also ask
which are causing the most grief.
I'm using java 1.4.0 very happily with Tomcat 4.
As was pointed out below, this was actually a problem with Tomcat anyway.

Re: RE : java.lan.OutOfMemoryError
Posted by Jeff Larsen <la...@qec.com>.
Actually, changing java versions is easier than changing Tomcat versions.
I've made it my policy to NEVER use a Java 1.x.0 version. It never pays
to be on the bleeding edge. If you've ever spent any time hanging out in
the Java Developer's Connection 'Bug Parade', you'll know that they rarely
get anything right the first time.
My advice is to go back to JDK 1.3.1. There's nothing about Tomcat that
requires 1.4.
Jeff

Coo - is your whole LAN out of memory? Wow! (Sorry couldn't resist.)
Seriously: You using JDK 1.4? We found that TC 3.2.3 with JDK 1.4 was
giving us a recursive IllegalStateException which locked up the server
and eventually fell over.
Reason: Any cancelled or closed HTTP request would apparently cause
this problem. Seems that this causes the output stream to be closed and
under JDK 1.4 any attempt to write to it causes an
IllegalStateException.
Closer investigation showed that the error handling in 3.2.3 was fairly
junky, (lots of empty exception handlers, hopefully addressed in 3.3/4.0
series) and it tries to handle by passing it to the error servlet, which
tries to write out the error, which gives an IllegalStateException,
which redirects to the error servlet, etc.
Solution: TC 4.01 does not exhibit this behaviour, so we upgraded.
Hope that helps

Coo - is your whole LAN out of memory? Wow! (Sorry couldn't resist.)
Seriously: You using JDK 1.4? We found that TC 3.2.3 with JDK 1.4 was
giving us a recursive IllegalStateException which locked up the server
and eventually fell over.
Reason: Any cancelled or closed HTTP request would apparently cause
this problem. Seems that this causes the output stream to be closed and
under JDK 1.4 any attempt to write to it causes an
IllegalStateException.
Closer investigation showed that the error handling in 3.2.3 was fairly
junky, (lots of empty exception handlers, hopefully addressed in 3.3/4.0
series) and it tries to handle by passing it to the error servlet, which
tries to write out the error, which gives an IllegalStateException,
which redirects to the error servlet, etc.
Solution: TC 4.01 does not exhibit this behaviour, so we upgraded.
Hope that helps

Thanks David! I'll probably be back on the list with questions about geting
TC 4.01 set up, but that answers MANY questions. After all, the application
worked fine a half year ago when it was developed. I've fiddled with things
in the meantime, and I thought maybe the configuration or code was broken.
Now I know what to try.

Hi all,
When I run my webapp from localhost, everything seems to be fine. When I put
a link to in on my website and try running accessing it from there, I get:
2002-03-22 12:47:12 - Ctx( /RobertDouglass ): Exception in: R(
/RobertDouglass +
/img/Beetle8.jpg + null) - java.lang.OutOfMemoryError
and Tomcat eventually crashes, but not before my data is corrupted.
I also get the following error:
2002-03-20 22:27:01 - Ctx( /RobertDouglass ): IOException in: R(
/RobertDouglass
+ /img/Beetle6.jpg + null) Software caused connection abort: socket write
error
where do I start looking to fix this?
Thanks,
Robert Douglass
