Hi,
we use apache2-mpm-prefork, can threading issues still be an explanation
for this kind of segfaults?
It seems rather complicated to backport version 2.0.8 to wheezy on my
first try.

Hi,
we are encountering occasional connection disruptions caused by segmentation
faults in xs/Apache2/RequestIO/Apache2__RequestIO.h Our application is a
PerlResponseHandler based on Catalyst::View::Mason on Debian Wheezy. The
segfault seems to always happen in mpxs_Apache2__RequestRec_rflush().
Sometimes we have NULL dereference, sometimes dangling pointers:
(gdb) bt
#0 0x00007fd145345728 in mpxs_Apache2__RequestRec_rflush

I would recommend trying mod_perl-2.0.8, and if you are able to test
things in a development environment separate from your main production
systems then the SVN trunk would definitely also be worth trying. The
latter contains some significant changes in the area of threading,
which I believe fix a number of possible SEGVs.
