Service Unavailable - Default App Pool is being Disabled
Posted on 2006-06-08
I've search the site for an answer and I can't narrow the result down to the problem I'm having. This is urgent because it stop my users from checking their email through RPC/HTTP and OWA.
The DefaultAppPool is being automatically disable. I restart the WWW Publishing service and all is well for an undetermined period of time (the last time I had to restart it was on 6/5/06.)
The event log reveals the following, Event ID 1011, Source: W3SVC, A process serving application pool 'DefaultAppPool' suffered a fatal communication error... The process id was '4768'. The data field contained the error number.
Also, the same Event ID of 1011 is seen again with a process id of '804', '1996', '7148' & '5448'.
Then an Event ID 1009, Source: W3SVC, A process serving application pool 'DefaultAppPool' terminated unexpectedly. The process id was '3188'. The process exit code was '0xc0000005'.
Finally an Event ID of 1002, Source: W3SVC, Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.
Previous events are close to the same as described above, Event IDs of 1011, then Event ID 1009 and then the 1002 where the Default App Pool is disabled.
