>Description:
At seemingly random intervals, clients receive error messages like:
Connection reset by peer
or certain parts of web pages fail to load (eg: 20% of images load, the rest show broken images).
The server error logs show no indication of what's going on, and it is nowhere near being
overloaded with around 8 requests/second and .0131% CPU load
>How-To-Repeat:
Due to the seemingly random nature of the problem, it is a bit difficult to reproduce. You
can try: http://partyman.qc.ca
to see if you can reproduce it.
>Fix:
>From what I've been able to gather, I believe this is either a problem with glibc 2.1
or openssl. I have a few servers setup with libc5 which have never had so much as a hiccup,
and I've had a few problems with different software packages and glibc 2.1
