Tomcat pausing by some strange error

["Yifan (Eric) Jiang" <e....@auckland.ac.nz>]

Hi all,

 

I've installed Tomcat 5.5.23 on a RedHat AS 4. Tomcat is communicating
Apache by mod_jk.

It just stop running last night and I have to run it again today's
morning.

 

I've found some messages from Tomcat log file, catalina.out.
