I notice on a system with SLES 12 that the "load average" is very high:
top - 10:17:13 up 1 day, 17:26, 1 user, load average: 1251.61, 999.30, 752.61
Tasks: 3324 total, 1 running, 3322 sleeping, 0 stopped, 1 zombie
%Cpu(s): 5.8 us, 5.5 sy, 0.0 ni, 58.3 id, 29.8 wa, 0.0 hi, 0.6 si, 0.0 st
KiB Mem: 33012816 total, 32728924 used, 283892 free, 81932 buffers
KiB Swap: 31456252 total, 77724 used, 31378528 free. 27046296 cached Mem
There are almost 3000 'kworker' kernel threads forked/running:
# ps -ef | grep kworker | wc -l
2914
The machine is a box with 20 CPUs and is currently under load but that seems a bit too much of it.The box is responsive et al, it's just that a migration to SLES 12 implies our monitoring to be completely reconfigured then.
Is that considered "normal"?
