[Mono-dev] xsp error (temporary interruption)

[Carlos Solorzano]

We thought our web server went down, all web requests were failing, then 
as I am starting to look at the problem it all started working again on 
its own, XSP had the output below, any ideas what might have caused 
that? we are running mono and xsp 1.1.10.1 on gentoo 32bit (2.6.15 
kernel) and no idea if its reproducible or not, we don't even know what 
was going on when it happened.
