Tomcat stops working after a few days!
Hi,
I have a problem running Jakarta Tomcat 4.1 port under FreeBSD 4.4 with
Blackdown Java 1.3.1 with mod_jk 1.2:
After startup.sh /logs/catalina.out shows up following lines:
[INFO] Registry - -Loading registry information
[INFO] Registry - -Creating new Registry instance
[INFO] Registry - -Creating MBeanServer
[INFO] Http11Protocol - -Initializing Coyote HTTP/1.1 on port 8080
Starting service Tomcat-Standalone
Apache Tomcat/4.1.24
HTTP Tunnel connected to the DigiChat server localhost
HttpTunnelingServlet connected to the groopz server
[INFO] Http11Protocol - -Starting Coyote HTTP/1.1 on port 8080
[INFO] ChannelSocket - -JK2: ajp13 listening on 0.0.0.0/0.0.0.0:8009
[INFO] JkMain - -Jk running ID=0 time=7/21
config=/usr/local/jakarta-tomcat4.1/conf/jk2.properties
[INFO] ChannelSocket - -server has been restarted or reset this
connection
[INFO] ChannelSocket - -server has been restarted or reset this
connection
[INFO] ChannelSocket - -server has been restarted or reset this
connection
[INFO] ChannelSocket - -server has been restarted or reset this
connection
The first days everythings runs correctly. The example servlets can be
executed via port 80 by help of mod_jk.
After a few days suddenly the servlets cannot be executed anymore.
Having a look on the Tomcat process with "top" prints out state
"sbwait".
That state does not change anymore AND I cannot shutdown the tomcat
process by help of shutdown.sh - so I have to kill the process with kill
-9.
"catalina.out" meanwhile has grown up to nearly 1MB because a lot of
lines (content: [INFO] ChannelSocket - -server has been restarted or
reset this connection ) have been inserted.
Killing and restarting Tomcat manually and restarting apache afterwards
for activating mod_jk again results in making all work again.
Does anyone have an idea of what is happening here?
Thanks and regards
Volker

This seams to be a still present bug of mod_jk2 java sources. Aparently, the
only way to define that property, "serverRoot" is to define and export it as
an environment variable in one of the satrtup scripts, "catalina.sh" or
"startup.sh".
Nix.

I added it to catalina.sh and got rid of the message.
serverRoot=/blah
export serverRoot
Not sure if the explicit export is needed I put them both in at once.

I said before, as I learned from another guy on this list, jk2 configuration
files on the Tomcat side do not support "serverRoot". Actually, you can
define and use it in ${CATALINA_HOME}/config/jk2.properties, but the
"jkjni.so" modules will not pick it up (and those are complaining), unless
you define it as an environment variable.
Nix.

I said before, as I learned from another guy on this list, jk2 configuration
files on the Tomcat side do not support "serverRoot". Actually, you can
define and use it in ${CATALINA_HOME}/config/jk2.properties, but the
"jkjni.so" modules will not pick it up (and those are complaining), unless

This seams to be a still present bug of mod_jk2 java sources. Aparently, the
only way to define that property, "serverRoot" is to define and export it as
an environment variable in one of the satrtup scripts, "catalina.sh" or
"startup.sh".
Nix.

Re: Tomcat and native libs.
Posted by Christopher Williams <cc...@ntlworld.com>.
I'm no Unix expert, but I believe that signal 11 is a segmentation fault
(i.e. you're accessing either an invalid memory address or one which you are
not allowed to use). The most likely cause is a NULL pointer access. What
you could try doing is handling signal 11 in your code. In the remainder of
your native code you could set a global variable to the name of the current
function being executed and your signal handler could print this to STDOUT.
Then at least you can start to isolate where the problem is occurring.
Do something like the following:
#include <signal.h>
#include <siginfo.h>
char *g_currFn = "";
if (SIG_ERR == sigset(11, handler)) {
// Bummer...
}
...
void handler(int sig) {
// Print signal and offending function to STDERR
psignal(sig, (const char *) g_currFn);
}
int myfunc(int) {
g_currFn = "myfunc";
...
}
Something that is eminently possible is that your native code is relying on
a Java class that is, say, in $JAVA_HOME/jre/lib/ext and is being loaded by
the standard Java classloader but is not being loaded by the Tomcat loader.
In this case the call:
jclass clz = env->FindClass("example/somewhere/something/ClassIWant");
jmethodID mid = env->GetMethodID(clz, "<init>", "()V");
will access an invalid pointer and crash the virtual machine. I know; I've
done it.
Hope this helps.
Chris.

Hi Anton, sorry i haven't replied earlier. The native code is ok. It
works perfectly without Tomcat. It's related to reloading web
application. I've actually worked it out. But by taking a bit differen
way.

Hi,
>Have you tried synchronizing access to the native methods? Yes.
>Does Tomcat and the JVM crash when you only have one servlet using the
native code?
Yes, everything crashes when the first servlet gets the instance of
shared object. Lets say the shared object is called Data. The servlet
gets the Data instance by "Data data = Data.getInstance();" and in Data
object it looks like this: "private static Data instance = new Data();"
and then the getter method. Data in it's constructor tries to get access
to Tibco Rendezvous and create a session. And exactly at this moment
everything crashes.
>Alternatively, can you have two instances of the object so that it is
not shared?
No, i need to have it like this. This shared object gets the data, which
is then shared among other servlets.
>What are the messages printed by the JVM when it crashes?

It looks like. JVM says it's loaded. See the crash message. I've marked
the suspected library.
BTW, i've patched the system as it was suggested by sun. The funny thing
is that it runs without any problems if used without Tomcat.

Tomcat and native libs.
Posted by Daniel Kowalik <da...@reuters.pl>.
Hi, i've got a simple application with a couple of servlets using one
shared object. The problem is that this shared object uses native libs
and there is no way to avoid it. And whenever servlet gets the instance
of this shared object, Tomcat crashes and also crashes the whole JVM.
When i use this obejct outside tomcat, in a standalone application,
everything is ok. I've gave it a try on solaris and windows and in both
cases i've got the same results. Of course native libs are for sol and
win respectively. And here is the question: shall i somehow inform
Tomcat about native libs? (Theese are already on LD_LIBRARY_PATH
variable).
