Subject Re: Servlet killing tracking
Date Wed, 24 Apr 2002 17:21:35 GMT
My problem is not a deadlock. My problem is that the service is running on
an other computer 100km from me, it runs 24 hours a day, and sometines
(rarely) it crashes because Tomcat killed the servlet.

So I can only debug using logs this king of bug tracking. Using a debug tool
is not possible...

Thanks for your help
