Hi, I made an Tomcat and JVM upgrade few weeks ago (to Tomcat 6.0.32 and jdk 1.6.0.24), and since that time I can notice a very strange behavior: sometimes, even once a day, Tomcat stops suddenly. There is no java process anymore, there is no errors in catalina.out log file, and, what is the most confusing, there is no hs_err_pid*.log file anywhere, or I cannot find it. Before upgrade, if jvm crashed, the hs_err_pid*.log file was always in root home directory.
In mod_jk.log I have only this kind of message: [Thu May 05 01:10:38 2011] [16891:140430015608640] [info] ajp_connection_tcp_get_message::jk_ajp_common.c (1223): (worker1) can't receive the response header message from t omcat, tomcat (127.0.0.1:8009) has forced a connection close for socket 15 [Thu May 05 01:10:38 2011] [16891:140430015608640] [error] ajp_get_reply::jk_ajp_common.c (2055): (worker1) Tomcat is down or refused connection.

Tomcat is probably not started or is listening on the wrong port (errno=111) In other words - I cannot find any trace of tomcat crash in any log. Can you help with looking for it? Maybe hs_err_pid*.log is in some not obvious place.
