we have two QNAP TS-1635 NASes (one per location), running at identical configuration and firmware versions. However, one of them has ever higher and higher load averages and actually needs to be restarted every week once load averages get too high so that our monitoring gives it a rest.
There is nothing in htop
, iotop
or iftop
showing up that could explain the high values; also dstat
doesn't show anything (here I only show an excerpt, nothing really changes):
# dstat -cdngylr
--total-cpu-usage-- -dsk/total- -net/total- ---paging-- ---system-- ---load-avg--- --io/total-

What could explain the load averages going continuously up? It's not used for anything except afp/smb storage for TimeMachine. All disks are SMART OK, and no errors/warnings show up in dmesg
.
