I got Open too many files error when I set the max open files 4096, so
that I changed it to 9182. But I think no matter how large it is, it won't
affect the performace, right?
I'm not good at Java. But I don't think I reloaded the classes in Tomcat
manager. I didn't change web.xml. Is it the

Hi,
I have stunk on this problem for almost 2 weeks. :-(

When you get java.lang.OutOfMemoryError: unable to create new native thread
it means you are running into an operating system limit. You can give the JVM
1 Exabyte of memory and you'll still get this error.
Look at the kernel parameters for your machine and the following limits:
1) Threads
I am using Linux2.4.20-smp. I think the limits for the entire system are
not problem:
cat /proc/sys/kernel/threads-max
14336
cat /proc/sys/fs/file-max
209708
cat /proc/sys/fs/file-nr
22311366209708
ulimit -a
core file size(blocks, -c) 0
data seg size (kbytes, -d) unlimited
I would hunt the archives, I did a search for outofmemoryerror native and saw
this - I am sure there are more similar threads with this issue:

If _POSIX_THREAD_THREADS_MAX=64 - then you would have problems since that
means tomcat
