IIS restart causes many Connection_Abandoned_By_AppPool messages in log
- by PP
After about half a day the IIS 6.0 ASP (VBScript) web server appears to die. It accepts TCP connections (i.e. I can telnet localhost 80 successfully) however it does not return any response.
When I restart the server (going through My Computer - Manage - IIS - All Tasks - Restart) I get a lot of entries in C:\WINDOWS\system32\LogFiles\HTTPERR\httperr1.log at the time of restart that say:
... 80 HTTP/1.1 GET / - 843545307 Connection_Abandoned_By_AppPool DefaultAppPool
... 80 HTTP/1.0 GET / - 843545307 Connection_Abandoned_By_AppPool DefaultAppPool
... 80 HTTP/1.0 GET / - 843545307 Connection_Abandoned_By_AppPool DefaultAppPool
where the ... refers to the prefix of the line, e.g.
2010-03-17 10:05:06 127.0.0.1 4927 127.0.0.1 80
There are 583 such lines (Connection_Abandoned_By_AppPool) in my log at time of restart.
What could be the cause of this problem?
