Urgent: Child process closed admin channel on Solaris 9 and 6.1 SP5
Hi
I'm facing this issue on Solaris 9 and Sun AppServer 6.1 SP5, the appserver crashes for some reason and restarts itself. There doesnt seem to be any specific instance which leads to this error. I notice that if I leave my application running for a while I end up seeing this error and I need to kill the instance that was running and restart the server instance.
This is what i see in the log files before the server restarts itself.
" failure (12181): CORE3107: Child process closed admin channel"
It seems like i'm not the only one seeing this issue:

Anybody knows what could be going on?
Thanks

Others have certainly seen that same message, but the message is only a symptom. That message will be logged whenever the child webservd process crashes. Such crashes are usually the result of buggy plugins.
If you want to try to debug the issue yourself, you can look for a core file in the server's config subdirectory. You can use pstack(1M) to get a stack trace which may help identify what is causing the crash.

After the corefile is written, use pstack on it. In the pstack file you a stacktrace of the crashing function. Alas, this information is only useful when you have the sources.
Also, usually there are other, more specific lines in the errors logfile e.g.:
[27/Jan/2006:07:38:55] catastrophe (15456): CORE3260: Server crash detected (signal SIGSEGV)
[27/Jan/2006:07:38:55] info (15456): CORE3262: Crash occurred in function INTprepare_nsapi_thread from module /opt/SUNWwbsvr/bin/https/lib/libns-httpd40.so
[27/Jan/2006:07:38:55] failure (15455): CORE3107: Child process closed admin channel
If you post them, maybe somebody can give you a hint...
