Subject Re: Tomcat dies suddenly

Just an update.

After 8 1/2 days, on the newly built Slackware machine with the JRE in the 
Slackware distribution removed bebore installing the operating system and 
using the newest version of the mysql-connector, the system failed in 
exactly the same fashion as the previous attempts: ran beautifully right up 
to the point of failure and the failure was the JVM being stopped with a 
reported seg fault.

Changed this server to the IBM JVM.  Tested it locally (directly accessed 
the IP within the DMZ) and it worked great.  Switched it to production early 
this morning (4:30AM before people start coming onto the system) and 
everything seemed good.  Then, specific customers (the rest were able to 
come in just fine) starting getting 404's (we use only https, didn't have a 
chance to see if they could come in as http) on their first access.  I 
switched to a backup server with the old configuration and everyone seems OK 
for now.

Remember, three servers:

A - Slackware 13 - 64 bit.  Latest IBM JVM.  Tomcat 6.0.24.

B - Slackware 13 - 64 bit.  Sun JVM 1.6.0_18.  Tomcat 6.0.24.

C - Slackware 12 - 32 bit.  Sun JVM 1.5.0_01.  Tomcat 5.5.23

A is the server I have been experimenting with.  B is the server I am 
currently running on and expect it to fail (because it always has.)  C is 
the original server that has run successfully for several years.

One more event that may or may not be related.  I have not touched the 
original server (C) except to roll new war's out (almost nightly... minor 
bug fixes.)  This morning, it started producing these messages every 10

Chuck, seems like it is time to break out the exorcism tools.
