I've investigated on my "deadlock" problem. It seems that this problem comes from GAMIN.
I explain:
I'm running a big (more than 50 aspx, ascx) web application. If I run a precompilation page (see the attached aspx.cs)
Mono, will compile about 20 pages, and will lock forever...
If you send a SIGQUIT to mod_mono_server you will obtain that some thread do :
- "" tid=0x0xb646bbb0 this=0x0x3893c0:
- in (wrapper managed-to-native) System.IO.FAMWatcher:gamin_MonitorDirectory (System.IO.FAMConnection&,string,System.IO.FAMRequest&,intptr) <0x4>
- in (wrapper managed-to-native) System.IO.FAMWatcher:gamin_MonitorDirectory (System.IO.FAMConnection&,string,System.IO.FAMRequest&,intptr) <0xffffffbf>
- in System.IO.FAMWatcher:FAMMonitorDirectory (System.IO.FAMConnection&,string,System.IO.FAMRequest&,intptr) <0x1f>
- in System.IO.FAMWatcher:StartMonitoringDirectory (System.IO.FAMData,bool) <0x7d>
- in System.IO.FAMWatcher:StartDispatching (System.IO.FileSystemWatcher) <0x192>
- in System.IO.FileSystemWatcher:Start () <0x17>
- in System.IO.FileSystemWatcher:set_EnableRaisingEvents (bool) <0x27>
- in (wrapper remoting-invoke-with-check) System.IO.FileSystemWatcher:set_EnableRaisingEvents (bool) <0xffba2006>
So the gamin_MonitorDirectory will never end and block all the other thread...
The only way to force compilation contunation is to kill gam_server...
The compilation will continue, compile 5 page, and will block again!!
I've tried to remove gamin from my linux...
and suprise!!!
It work well, without gamin!
Is there a way to tell mono, not to use gamin, for FAMWatcher, even if gamin is installed?
My version of gamin, is the last one: 0.1.7
I'will try to do a test case with many aspx files, to show you the problem!
Thanks in advance

Specifically, the @Page or @Control directive for the page/control that is being compiled and anything else that helps reproducing the problem. -Gonzalo
