Subject Re: Why does my MP2 crash intermittently?
Date Tue, 13 Sep 2005 08:55:06 GMT
Hello Stephane,

I've had a good tip from Mike (thanks Mike!) that the problem is Windows
related. Check out for details.

Although they claimed that it is a pre-SP1 problem, I'm running SP4 on W2K
and I'm still seeing it. Will try the same setup on W2K3 and see if the
problem persists.

My situation seems to be worse than yours. I have the following already in
my httpd.conf:
PerlModule Apache2::Reload
PerlInitHandler Apache2::Reload

But it did not change anything.
