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.

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. Regards, Rainer
