Hi Rainer,
We never face this issue with tomcat 8.5.32 and from 8.5.33 it will causing the
issue and it happen on both OS Window and Linux, it will be blocking for us
because we are not able to update tomcat to latest on and it had some security
issue fixed in it, please let me know how should I proceed from here.
Others have already pointed you at
https://bz.apache.org/bugzilla/show_bug.cgi?id=53492
This introduced a new feature to JspC to make the compilation
multi-threaded. Before this change it was always done on only one thread.
The good: it will make the compilation of your many JSPs faster.
The bad: it seems to create a yet to understand new problem for you.
I suggest you follow the hints, that I gave in my previous mail.
Regards,
Rainer
Thanks and Regards,

Hi Mark,
I am suspecting the same in 8.5.33 tomcat, do you still won't me to
check it on tomcat 8.5.33?
How about increasing your perm memory?

Hi Team,
We have precompileJSPs tests that include compilation of around
4000 jsp files. After upgrading to Tomcat *8.5.34* from Tomcat
*8.5.32* we are facing an *Error:*/java.lang.OutOfMemoryError:
unable to create new native thread /
The machines on which tests were executed have *16GB* of RAM, out
of which around *13GB* was free.
The precompileJSPs tests were executed on Tomcat *8.5.34* by
setting ANT_OPTS from -Xmx4096m to -Xmx10240m, But Still the result
was /OutOfMemoryError./

However, We successfully tested precompileJSPs tests for Tomcat
*8.5.32 *with ANT_OPTS as -Xmx384m
Can someone please have a look into this issue?
Have you looked at the change log for the changes between 8.5.32 and
8.5.34 that might be relevant?
It could be changelog in 8.5.33

Have you tried testing with 8.5.33 to narrow down the version in
which the issue first appears?

You can control the number of threads using -threadCount. By default the number
is equals to the number of cores the operating system show to the JVM. You
might want to use a smaller number to see whether that helps.
I suggest you also check your Linux system limits on processes per user.
That system limit on Linux in fact limits threads per user. So if such a limit
is set and your user has other processes with many threads running, you might
need to increase this limit.
In addition you can run your ant process with
strace -f -o /var/tmp/strace.out HERE_COMES_YOUR_ANT_COMMAND &
Then after you get the error, you can check the strace.out file for system call
errors. The file will be big, but most probably the error is relatively close
to the end.

Rainer
