We've got some issues with mono 2.0 (it seems like Preview 2 or RC1,
compiled from SVN 2.0 branch).
1) In rush hours mod_mono server didn't close the connections, and
hundreds or even thousands open connections "kill" the server. In
error_log there are only messages like "[warn] child process 12467 still
did not exit, sending a SIGTERM". It happens in random manner several
times per day in rush hours. Just number of open connections starts grow
2) May be related to 1) - mod_mono processes grow in time (I mean memory
consumption). And sometimes reached 1-2 Gb for most loaded web-sites.

Could anyone point the reason of these issues?
We are waiting for Mono 2.0 RC2, but not sure it fix the problems.

P.S. We use CentOS 5.2 x64 and Apache 2.2.9 (the same issues with 2.2.3).
