32 Bit Win2008 Server Webedition OS, 8 GB RAM, 2x2,4 GHz Xeon
IIS 7,
CFMX ColdFusion Enterprise 8.0.1(195765) Server configuration,
Java Version 1.6.0_04, Macromedia JRun 4 (Build 108487)
About once a week ColdFusion hangs completly and cf-pages are not delivered (Server Error 503).
The ColdFusion adminstrator is also not available (neither remote or on the server itself).
Static html- and aspx-pages continue to be delivered (the IIS and ASPNET Applications are available).
There are no high loads on the server on either processor or memory.
The log-files doesn't show anything to be concerned about, in fact nothing. The CF-Server hangs without issuing any log entries or windows events. In two cases, a restart of ColdFusion (without a server reboot) resulted in the same behaviour 30 minutes later.
Memory usage in CF system monitor is normaly about 180MB with peaks around 260 MB.
Normaly we got a memory usage around 200 KB in session scope by 300 sessions/users.
So all in all the server is not used very heavily and appears to be running normally.
We've got no idea what happens. The only thing we notice is a possible influence by the application pool settings in the iss7. Initially we set the application pool to the default integrated mode. The server hung after about a week.
After the second time, we changed the pool setting to classic mode hoping this might help. Again after about a week the server hung. We then went back to integrated mode and the server then hung again within 30 minutes.
Up till last week, we thought this was being caused by the ODBC drivers for the Oracle 8i DB connection. However these have been replaced by OCI drivers now which seem to be performing OK.
Unfortunately, we have only gotten the crash dump settings set up yesterday so we don't have a dump at the hung stage yet.
Has anyone any idea or experiences with CFMX8 and win2008/ISS7 that could shed light on this behaviour?
Greeting
- Thomas
