Well first off, the main one that was having this issue was a Ubuntu box. That one is still active but I wanted to replicate the issue so I did a Debian Virtual Machine and I get freezing on both, no resets yet. Comparing the VM to the production box, only one graph froze on the production, while two graphs froze on the VM, one of which was the same graph that froze on the production, but they froze up at different times. I'm not sure how to get what you're asking for, but I tried how I normally debug bash scripts and did the following:<br>
<br>root@debian:/etc/mrtg# sh -x env LANG=C /usr/bin/mrtg /etc/mrtg/mrtg.cfg --logging /var/log/mrtg.log<br>sh: Can't open env<br>root@debian:/etc/mrtg# sh -x /usr/bin/mrtg /etc/mrtg/mrtg.cfg --logging /var/log/mrtg.log<br>
/usr/bin/mrtg: 17: Syntax error: "(" unexpected<br><br>Given that I'm getting similar symptoms on both machines, I think it's safe to rule out corrupt filesystems and possibly permissions. But looking at permissions in the web folder, root is the owner of all files in there with 644 permissions on all. Under the MRTG folder where the cfg and scripts are, all scripts are owned by root with 755 permissions. Some scripts call text files that were transferred from another server to get their values, those .txt files are again, owned by root with 644 permissions. The cron job that runs MRTG is under root's cron. The only thing that I see that doesn't quite match up is that apache2 runs as www-data. Could that be it? I don't see why it would play in to it considering MRTG is being run as root to modify files owned by root.<br>
