Bug ID: 194525
Summary: Restart Apache Causes page fault and kernel dump
Product: Base System
Version: 10.1-RC2
Hardware: amd64
OS: Any
Status: Needs Triage
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: p...@nomadlogic.org
On a 10.1-RC2 system where I run apache24 I seem to be reliably able to cause a
kernel panic and system crash while restating apache24.
I run mod_wsgi on my apache instance for serving graphite webUI. I have not
been able to detect any hardware defects on this system at this time.
Here is the output from /var/crash/panicmail.0. I can make all other related
cores etc. avail upon request:
> sudo cat panicmail.0
