OutOfMemory Error in Catalina
Hi All,
Now a days i am stuck with a problem. I get exceptions in Catalina.out log file when my web application is running on that.
Is there any utility to find out, from where or from which files the memory is leaking...
For your information, putting the exception here...

I bet your going down the wrong path for debugging, from the FAQ:
-- You have too many threads running. Some OS's have a limit to the number of
threads which may be executed by a single process. (Which is what the JVM
is.) Refer to your OS docs for more information on how to raise this threshold.

I was suggested one more way is to increase the server's maximum file descriptor limit. But I don't know where to increase this limit. Apart from that, is there any other way / utility to find out the root cause of OOM in catalina.out log file.

Hi,
I tried to increase the heap size to 1200 MB in catalina.sh file (JAVA_OPTS="-Xms64m -Xmx1200m"), It didn't work. I was suggested one more way is to increase the server's maximum file descriptor limit. But I don't know where to increase this limit. Apart from that, is there any other way / utility to find out the root cause of OOM in catalina.out log file.
