TOMCAT crash

[Rakesh Gadre]

We are using Apache 2.2 and Tomcat 5.5.16 on UNIX.

The application was working fine and all of a sudden Tomcat crashed!! Here is the log:

[Mon Aug 20 11:35:33 2007] [info] ajp_service::jk_ajp_common.c (1721): Receiving from tomcat failed, recoverable operation attempt=0

Any clue?

Is there anything else under TOMCAT_INSTALL/logs?

Nope

At this point I would be using the Manager application to look at how many Threads Tomcat is using and how long they have been running.

If you have somehow used up all the allocated Threads, Tomcat will refuse connections. I once got bit by this when request handling Threads started going into endless waits due to bad configuration.
