Worrying error messages

Should I be concerned at these two errors received within a couple of minutes of each other to my admin email from cron:

Cron [email protected] sudo /usr/local/hestia/bin/v-update-sys-queue restart
Segmentation fault

Cron [email protected] sudo /usr/local/hestia/bin/v-update-sys-queue restart
double free or corruption (out)

Quickly checked the server, and everything is up on Hestia’s server list page - but is this a sign that something is fundamentally wrong and the server is about to die?



And this just through:

Signal 11 (SEGV) caught by ps (3.3.12).
ps:ps/display.c:66: please report this bug

Email seems to have gone down on the server, even though Hestia says it’s up

not enough information. especially about your server/setup. is this ovz/lxc by any chance? probably running out of memory and/or the OOM-reaper is killing processes.
have you set up some swap at least?

Ubuntu 18.04 LTS 64bit
Intel Xeon E3-1240 v2 8 core
32GB RAM / 480GB SSD

KiB Mem : 32909600 total, 1525096 free, 2997508 used, 28386996 buff/cache
KiB Swap: 999420 total, 977404 free, 22016 used. 29361356 avail Mem

Not sure what ovz/lxc is, but if you tell me where to look I can find out.



I see. I was expecting this to rather be a vps and not a dedicated :wink:

OVZ/LXC are containerization methods (as opposed to KVM for full virtualization). obviously that doesn’t apply here then and the RAM usage also is fairly low.

yes, a segmentation fault is nothing you want to see then. if possible, maybe restart into rescue mode and run some memtest …
