Hello,

I switched to a new opensuse 12.3 server recently and installed the mono
3.0.4 package with mod_mono 2.10-11.1.1. the application was running fine
for over a year before on the old server.

In order to run the application on the new server, I had to fix the
mod_mono_server path like described here
http://stackoverflow.com/questions/14244779/unable-to-run-an-asp-net-4-5-app-on-xsp-on-mono-3
.
Then it all looked nice, webapp worked, until I noticed at some point the
application won't reply to my requests.


I tried different appache server tuning settings and mono restart
settings.  Then I noticed that the app crashs exactly when mono trys to
restart it either by the "Time" or "MonoAutoRestartRequests" setting.

I set the limit then to 150 requests, checked with the mono control panel
page and after 150 requests it stopped working.
Any ideas how to fix that? Can I provide more info?

The only thing I see in the apache error log is this entry, multiple times
when restarting apache.

sending a SIGTERM

Best Regards
Patrick
