It looks like mono was running out of wapi handles.

I don't know which is the max handle count or whether
all handles share the same table. For the latter,
the error may be unrelated to threading. Maybe you
forget to close some files after each request.

I've patched mod_mono to do this. It's not bullet-proof,
but it works for us. Take care to always remove all
lock files /tmp/mod_mono* file before starting apache.
