 Subject:  m0n0wall on ALIX kernel panicing and rebooting
 Date:  Tue, 09 Dec 2008 15:40:31 -0500
I am seeing random kernel panics and reboots on a m0n0wall v1.3b15 on ALIX
3-port boards (again) but at a different client's site.I found this issue
posted by others here:


As well as my posting about this to the m0n0wall mailing list in March 2008 here:


Making the changes to this dns server mentioned in that thread has not fixed
this issue at this site.

Then system completes the boot and runs normally for a random time.

Where are some good places to start debugging this so that I can get my client
back to 100% Internet uptime?    This is getting to be pretty ugly with the
firewall rebooting randomly every few hours.

A posting from Manuel about this back in March pointed me to a vmstat compile
for 1.3b11... Is there a 1.3b15 vmstat available? Can I run the 1.3b11 one on
this 1.3b15 version?


Also, I was thinking that I could monitor the number of states by uisng wget
to post the  "ipfstat -s" command to the firewall via exec_raw.php file but
that is surely not the correct method since I need to parse and log the output
for tracking.   help?  :)
