Error in Jmeter Log (Can't connect after 10 retries, java.net.BindException: Address
already in use: connect )
Hi ,
I am load testing our webapp that uses JSF 1.2 using HttpRequest
Samplers . In my test Sampler A should come before Sampler B. When I ran
the test with 300 users I got into a situation where Tomcat was handling
sampler B but the debugger was showing that things were not initialized
properly and we got an exception . On further debugging it seemed that
Sampler A may have been fired but probably was not served by Tomcat . (
I can say so because of the log statements that i have put in my code ) .
First of all is kind of situation possible ? If yes , how ?
Secondly at the time when I got the exception , I saw in the JMeter log
entries like :
2011/08/25 14:47:42 ERROR - jmeter.protocol.http.sampler.HTTPJavaImpl:
Can't connect after 10 retries, java.net.BindException: Address already in
use: connect
What does this mean ? Tomcat is listening on 8080 in my case .

are you running the JMeter proxy server by any chance while running your
actual test. (I thought the sampler were implemented by HTTPSampler or
something like that not HTTPJavaImpl)

Mmmh - because in my experience with JMeter and all other threads regarding
BindException, we didn't have the particular use case you described, yet we
still ran into this exception. So are they related? Only if it explains why
you can't reuse the connection.
One more idea: untick "keep-alive" in Jmeter sampler, if you're using it.

Hi ,
Even if such a situation occurs how does it explain what I am
seeing as I explained in my first question ?

Hello,
This issue is about your client side system-configuration, rather than
JMeter issue. However, since a multi-threaded test plan needs lots of
connections to run, you can easily exhaust max connections, at which point
it will try and reuse connections - so this relates on what you are doing
with JMeter (OS, application under test, test plan). It doesn't seem
related
to your question, its an error about available outgoing sockets on client
machine rather than listening ports on the application server (hope they
are
not the same machine ;) in your case).
So start looking at this from this angle and if you can't figure it out,
see
if you can quick fix it by increasing the available connections (any OS)
or
file-descriptors (for linux is also required, each socket uses 1 file
descriptor).
On the long term you should consider why you need as many connections as
you
are using - if you actually need as many, it isn't best practice to use
"too" much (whatever is "too much" in your case).
Regards,
Adrian

Hello,
This issue is about your client side system-configuration, rather than
JMeter issue. However, since a multi-threaded test plan needs lots of
connections to run, you can easily exhaust max connections, at which point
it will try and reuse connections - so this relates on what you are doing
with JMeter (OS, application under test, test plan). It doesn't seem related
to your question, its an error about available outgoing sockets on client
machine rather than listening ports on the application server (hope they are
not the same machine ;) in your case).
So start looking at this from this angle and if you can't figure it out, see
if you can quick fix it by increasing the available connections (any OS) or
file-descriptors (for linux is also required, each socket uses 1 file
descriptor).
On the long term you should consider why you need as many connections as you
are using - if you actually need as many, it isn't best practice to use
"too" much (whatever is "too much" in your case).

Adrian
