Gaps in the Server Status graphs

[givan]

Hi,

During running backup tasks today and checking the PBS server to see how it copes, I noticed something odd - the graphs on the Server Status page have some gaps, just looking at the last hour when I know for sure the server wasn't rebooted or anything, it was just running a bunch of backup jobs.
Has anyone else encountered this issue or has a reasonable explanation as to why it happens?

P.S. - running the latest PBS version, updated earlier today, here's the list of packages:

is there anything visible regarding rrd in the logs (journal/syslog?) during that time

Looking around the syslog between 18:00 and up to 21:59, there doesn't seem to be anything obvious:

can you post the full journal/syslog of such a timeframe where the graphs are missing? maybe there is some hint in there..
