org.apache.tomcat.util.threads.ThreadPool#logFull(..) prints the following message: Jan 28, 2011 10:43:16 AM org.apache.tomcat.util.threads.ThreadPool logFull SEVERE: All threads (200) are currently busy, waiting. Increase maxThreads (200) or check the servlet status From the message it is not clear, what pool was exhausted. It might be that there are several connectors in the configuration. It would be better to assign name to the pool (the #setName() method already exists there) and to print that name. At least it is possible to print a stack trace: that will provide some information.
