Hi, I have a series of relatively high transaction volume tomcat servers which are sporadically hitting thread issues. We run with with tomcat 4.1.27 at the current time. The behaviour we notice is after several days of around one hundred thousand transactions our tomcat instances hang with the catalina.out message of:
SEVERE: All threads are busy, waiting. Please increase maxThreads or check the servlet status75 75 Stopping service Tomcat-Standalone I've done a quite a lot of reading on this and in some cases there is an indication that moving to a later tomcat version alleviates the issue. However in many others it indicates that this problem is due solely to the code whereby the threads are not exiting cleanly. We have a classic 3-tier architecture and we can see the db connections closing. I have tired reproducing this error on a tomcat 5 environment and I get a similar but not identical error: org.apache.tomcat.util.threads.ThreadPool logFull SEVERE: All threads (15) are currently busy, waiting. Increase maxThreads (15) or check the servlet status The tomcat install continues to function correctly after this has occurred. What I would like to know is do the 2 error messages correspond to the same underlying issue. I strongly suspect it is an application code issue so I would like to be able to count Tomcat out of the loop.
