I have rather extensive silverlight application with which our customers work.
Currently we have an issue where the application pool will crash with the following message:
"A process serving application pool 'app pool 1' suffered a fatal communication error with the Windows Process Activation Service. The process id was '6308'. The data field contains the error number."
When I try the same action on local, it works perfectly. When I try the same action on a difference application pool, it works perfectly.
Here's a bunch of stuff i've tried already:
- Change app pool 1 to app pool 2 in crashing application. Still crashes the app pool
- Duplicated the application from visual studio and put it on a different app pool (app pool 2). Works perfectly, when set to app pool 1, works perfectly
- checked all settings (app pool + advanced settings, website + advanced settings). Everything is the same
- Turned on Process Monitor, but it didn't show me anything usefull.
I have no idea what to try next to fix this problem!
Anyone have any suggestions?
ps. sometimes I get the following error in Windows Logs > Application, but since we are running a lot of applications on the server I can't see if it applies to this problem or not
