Default Server restarts

[Arvind Shukla]

I have noticed with WAS4.0 on Solaris and Win2K, that after some time (hours or even days) , default server stops then starts automatically, giving these kind of messages
[02.10.23 18:49:36:968 JST] 22d6376f ActiveServerP A ADMS0028I: Starting server: Default Server
ActiveServerP A ADMS0032I: Started server: [02.10.23 18:49:37:062 JST] 22d6376f Default Server (pid 2924)
Is this a normal behaviour of WebSphere? Any idea ???
Last time it happened when users were accessing the application, though it took hardly few seconds but application went down temporarily. Is it possible to disable this ?

Hello Arvind
well as on Winnt i have noticed that the restert occurs when the system is running out of memories.. thats cause its a microsoft product.. when you install WebSphere on Winnt, and the system is running out of memory, then what windows will do is pick up any java.exe process running and kill it ..
no wonder the war between microsoft and java is affecting IBM

Hi:
From your mail I couldn't make out the exact reason but I knows one case in which it happens.
If you are touching any files inside InstalledApps directory, then websphere admin server brings that appserevr down, so that it can be re initilized. But due to nanny process, It comes up in 5-10 seconds again.
This is normal behaviour of WebSphere. This happens on all the platforms.

Nah, you can turn it off by setting reload=fasle;/

Hi,
admin server executes ping for every constant time to an application server.
An application server is made to restart if there is no response to ping.
I think that this specification of WebSphere is the cause of these phenomena.
Thanks,

Yes i face the some what same issue, but that was when i tries to process transaction having large amount of data. at that time server or rather servlets restarts its process, i tried tracking the issue using trace logs and i found connection timed out, getting new connection errors, is this somehow related to DB timeouts? does websphere maintains a persistant connection with the DB Server, i m using DB2/400 on AS400.
