Segfault errors in log

[Vengance]

Hello,

I just noticed that dmesg shows several segfault errors in the log on our HP DL360p G8.

Is this anything we should worry about?



Thanks!

Is this anything we should worry about?

depends:
* the process-names (PLUGIN[diskspac], DBENGINE, ...) don't look like they're from a regular PVE installation (guess you have netdata running on the machine) - how is netdata installed - maybe the installation is corrupt, has a bug, ... ? (see e.g. https://github.com/netdata/netdata/issues/6356 - for a maybe similar problem)
* if you have segfaults also from other software (e.g. stuff installed via apt, or provided by the installer) - I would suggest to run a memory test on the system (it could point to a faulty memory module, or power supply, cable,...)

I hope this helps!
