I'm having some strange issues with mod_mono on my server at the moment. Sometimes while using the blog site, my apache2 server suddenly starts giving "server is down for maintenance" errors.
Checking the apache2 error log I'll find an error like this:
[error] (107)Transport endpoint is not connected: write_data failed
[alert] Failed to send initial data. Transport endpoint is not connected
This clearly shows that the apache2 process is no longer talking to the mod_mono process. Restart the apache2 server, and you start seeing errors like this:
Failed to destroy the '/tmp/mod_mono_dashboard_XXGLOBAL_1' shared memory dashboard
File exists: Failed to create shared memory segment for backend 'XXGLOBAL'
The best information for the problem I've found has been here, but unfortunately no solution as yet.
Hopefully I'll figure it out soon. This particular issue is serverely testing my patience at the moment. So if the blog is down, I appologise, we are attending to the problem :P
