Hi All,
I have encountered a problem when using Tomcat4.1.29.
I changed the appbase to my appliaction's directory (not in $TOMCAT_HOME/webapps) and add a context like this:
<Context path=""
docBase="/usr/local/myapplication"
crossContext="true"
debug="0"
reloadable="true"
trusted="false" >
</Context>
The application isn't a standard webapp. There is no web.xml in the application's directory.
Everything works well after staring the Tomcat.
But after 2-3 hours, the Tomcat will shutdown itself.
The catalina.out will record like this (I have modified the debug level to 8):

I recorded gc log, the records almost are FULL GC record like:
8341.069: [Full GC 491455K->314771K(519168K), 8.4939708 secs]

FYI some softwares related:
j2sdk-1_4_2_03-solaris-sparc.tar.Z
jakarta-tomcat-4.1.29.tar
64bit OS Solaris9 with Sparc CPU
MySQL4.0 (The problem arises even though I am not using the DataBase).
Any suggestion will be appreciated!
Thanks in advanced.
