MRTG is misbehaving: updates graphs once or twice, then stops.
A few hours ago I installed MRTG on a Debian Lenny server. It worked fine for about 20-30 min, then the graphs stopped updating.

I tried restarting the snmpd service, daemonizing mrtg, undaemonizing mrtg, pretty much anything I could think of to no avail. 'ps aux | grep mrtg' shows that it is still running - which makes sense as the graphs keep updating with zero values.

I tried running 'snmpwalk -v1 localhost -c public' to see if snmp wasn't feeding the data properly, but it seems to come back okay. /var/log/mrtg/mrtg.log also has absolutely no errors.

The only thing that gets the graphs to update properly again is to do a system reboot, after which the updates work for 2-3 times (10-15min) and then stop again.

Here's what the graph looks like now.

Any ideas? I googled the hell out of this but couldn't find any concrete ideas to try apart from running MRTG as a daemon.

Did you try with crontab and execute mrtg in a time interval?

I'm havin' the exact same problem.
I'm running:
Linux "my.server.domain" #5 SMP Wed Apr 1 13:09:49 UTC 2009 i686 GNU/Linux

I have tried installing it tree times and I have also formated it one time, without any luck.

I hope someone knows anything :)
