Zombie Processes
-
I'm running 4 pfSense 2.0 boxes of the Oct 18th build and they all seem to have something in common. That is they all have a bunch of zombie processes. It appears that the check_reload_status is not reaping it's children.

Yeah there were issues with check_reload_status around then. Update to a new build and it should be OK.

Awesome, thanks Jimp!

Hmm. I am still seeing this same issue on Thu Oct 28 03:32:27 EDT 2010 build.

I just checked and I'm seeing them also again. I'll pass it along.

Should be really fixed on new snapshots.
-
Cool, I will update and test.
Thanks.

Hi,
I'm running the beta4 with compile time "Sat Oct 30 19:40:13 EDT 2010" on an atom board and having the same zombie issues as described above.

I'm not sure that check_reload_status was rebuilt after that fix went in. I just rebuilt it by hand and restarted the builds. Try again after the next new snapshot.

Problem still happening as of this build: Thu Nov 4 01:20:42 EDT 2010 (i386)

I found the same issue on my system.so I installed the cron package from the pfsense GUI.
this is my cron list:
0 3 * * * killall check_reload_status
1 3 * * * /usr/local/sbin/check_reload_status -
Heh 'typo' was preventing the fix from actually being applied.
Newer snaps have the correct fix. -
Installed the update from 2010-11-09 16:xx (i386). The process count is no longer climbing out of control.
Thanks!
