I am not yet through with the issue that I had posted last time.Let me repeat the same with more detailed manner in this topic. I am working on a web application which uses Websphere 4.0 as a web server. I do development and testing on Test Server which has no issue what so ever. But Live server shuts down unexpectedly once or twice in a month which is obviously not desirable. After going through the logs, one thing I realized is that the Websphere tries to restart for some reason automatically and while restarting, it fails and stops suddenly.
The logs for the same are give at the bottom. Can anyone please give their thoughts on this? What makes the Websphere to restart automatically?
Thanks & Regards, Ketan

I tried to find out reason for my problem on other sites through google and came to know about these Websphere Timeout parameters. 1.ping interval, 2.ping timeout,and 3.ping initial timeout
Most of the places it was mentioned that increasing these parameters avoids the ping errors.These ping errors makes Websphere to stop and start again(which is happening in my issue).
But I am not getting through the definitions of these parameters. Can anyone please suggest which parameter should I increase in order to overcome my problem and upto what extent?
My default parameters for Websphers are 60 seconds for ping interval, 200 for ping timeout, and 300 for ping initial timeout.
