Hi, in the last days we've got quite problems with our application based on MapGuideOpenSource 2.2 (Windows Server 2008 R2, 64Bit). Periodically the MapGuideAppPool in IIS7.5 crashes. In Windows event.log there is the following message:
*A process serving application pool 'MapGuideAppPool' suffered a fatal communication error with the Windows Process Activation Service.* (Source = WAS) In Windows application.log I found that the cause of this message seems to be a defect of the module: *isapi_MapAgent.dll, Version: 2.2.0.5703* After five times getting this error the MapGuideAppPool is aborted. I think this belongs to the default setting of the MapGuidAppPool: If the same error occurs five times in a time span of 5 minutes the process automatically shuts down. In most cases a restart of the MapGuideAppPool in the IIS-Manager is sufficient to get the application up and running. In some cases I can't restart the pool in fact of a supposed running w3wp.exe-process. But there is no process anymore and at last I have to restart the whole server. I should also mention that there are no errors in other log files. Nor in the IIS-Log neither in any of the MapGuide logs. Even in trace log with full debugging enabled there is absolutely nothing at the time the error occurs. I realized that this error has been thrown over the last 6 months but not in this intensity that it leads to a crash. Maybe this has something to do with the growing number of users who have access to our application. As a workaround I changed the default settings of the MapGuideAppPool to 10 errors in 1 minute before aborting the pool. So, know I get only 1 crash per day (before 10 per day). Of course, this doesn't solve the initial problem. Does anybody else get these windows warnings/errors mentioned above? Or does anyone have any idea what could cause such an error and how to solve it? Maybe some extra settings for the application pool?
