Hello out here.
I did yesterday the last cvsupdate and compiled the system, a new
kernel, did a mergemaster.
The hardware is a older PII/350 (Dual), 512 MB RAM (dmesg output at the end).
Today I did a cvsupdate again to obtain the ip_fw2-code and test it.
But something strange happend to our system:
I do a make -j 8 world.
The load of the system runs temporarily up to 32!!!!!
This is the last top output I caught:
last pid: 58935; load averages: 25.40, 18.19, 14.46 up 0+15:26:59
11:02:47
197 processes: 28 running, 169 sleeping
CPU states: 81.2% user, 0.0% nice, 17.7% system, 1.2% interrupt, 0.0% idle
Mem: 128M Active, 272M Inact, 67M Wired, 15M Cache, 61M Buf, 18M Free
Swap: 1024M Total, 1024M Free
The system is just up right now and still in a useable state, sometimes it slows down
a bit due to the high load.
What's going on? I never watched a high load like the observed today, maybe a malfunction of
top? On the other hand: the machine is still in useable state and therefore its only a
question of couriosity.
Thanks.
Oliver
