Bug#449024: linux-image-2.6.18-5-amd64: general protection fault
Package: linux-image-2.6.18-5-amd64
Version: 2.6.18.dfsg.1-13etch4
Severity: critical
Justification: breaks the whole system
I am running a content filtering caching proxy server (Dansguardian + Squid).
After a day of successful run in production (not so much load - 8 local PCs), server suddenly hanged with the following error message on console:
Pid: 3888, comm: dansguardian Not tainted 2.6.18-5-amd64 #1
Server stopped responding to the pings and I could not ssh into the server.
The server runs on Intel Pentium 4 CPU 3.00GHz with 1G of RAM.
Here is a part of the log file, related to the problem:
