[Mono-list] mod_mono stability problems

[Oscar van Tol]

Hello,

For the past two months we've been hosting a webservice application on  
apache2 and mod_mono.
Since this week we have some real traffic, and stability issues  
started. We now have about 30.000 requests a day, these make the mono  
process grow in memory usage to about 2gigs. and the response becomes  
really bad.

The memory problem is probably cause by the none compacting garbage  
collector, I solved the performance issue by doing an autorestart  
every 400 requests. This works great for a while but after a few auto- 
restarts it lookes live apache failes to spawn a new mod-mono-server.
Apache respondes with a 503, when I kill the (old still running)  mono  
process and restart apache it's back.

Suggestions?
