I'm not sure what the conditions are for automatically restarting 
individual web applications, but you can restart mod-mono-server using 
the mod_mono control panel. See that section here:

http://mono-project.com/Mod_mono

I've written a command-line script (using links/elinks/lynx/whatever) to 
fetch the appropriate URL when I want to restart mod-mono-server.

There are two possible work-arounds. One the one hand, you could set up 
a cron job to restart mod-mono-server (as above) automatically at least 
daily.

Also, Marek has recently committed to svn some changes to mod_mono to 
provide three new directives:
     MonoAutoRestartMode Requests (or Time)
     MonoAutoRestartRequests 1000
     MonoAutoRestartTime DD[:HH[:MM[:SS]]]
to automatically restart mod-mono-server after a certain number of 
requests or after a certain amount of time. Those changes don't actually 
work for me out of the box (patch pending), but it may work for you. 
(You'd also need to install the latest mod-mono-server (xsp) from svn too.)
