Hi Robert,

I've updated Mono from
Issue like described occurs in previous version too, but in other manner
and not so often. It happens several times per week with records in
apache error log like:
Stack overflow in unmanaged: IP: 0x573940, fault addr: 0x496cddd8

Native stacktrace:
    /opt/mono/bin/mono [0x47e7a0]
    /opt/mono/bin/mono [0x4ada8d]
    /lib64/libpthread.so.0 [0x3e3e60e4c0]
    /opt/mono/bin/mono [0x47efbe]
    /opt/mono/bin/mono [0x47bf76]

Debug info from gdb:

[Tue Dec 08 19:21:23 2009] [notice] child pid 4911 exit signal
Segmentation fault (11)
[Tue Dec 08 19:21:23 2009] [notice] child pid 5566 exit signal
Segmentation fault (11)
After it nagios reported for all web-sites in this shared pool: HTTP
CRITICAL - No data received from host.
Other websites (more loaded) in isolated pools works just fine on both
Mono versions.

But also I have a goods news!  It seems like I've found workaround for
this issue. I've added line
to mod_mono.conf. And today all works just fine whole day long.
Of course we need to test it for about one week to say "YES!" :)

I think it would be great to rewrite page
http://www.mono-project.com/Mod_mono and describe such a situations more


With best wishes,
Max Karavaev
