Anyone else having stability problems when using Oracle & JDBCRealm?

Here is another piece of info I get from "catalina_log.2003-07-29.txt" when I try the 2nd restart (/etc/init.d/tomcat restart)

Tomcat is crashing every 2 - 3 days on 2 different Linux machines.
Both machines are running pretty much identical software configurations.
Both machines are serving the same web application so, it's almost certainly something in my web app code that causes the problem. However; the logs from my web app do not tell me anything.
I am seeing this error on 2 different Linux machines.
Tomcat just stops responding to my requests.
Also when I restart Tomcat (using: "/etc/init.d/tomcat restart"), I get this:
[EMAIL PROTECTED] root]# /etc/init.d/tomcat4 restart waiting for processes to exit [ OK ] waiting for processes to exit waiting for processes to exit waiting for processes to exit waiting for processes to exit waiting for processes to exit waiting for processes to exit waiting for processes to exit
The only info from logs I can find is from catalina.out:
