Greg>=20 Greg> Greg Hello Greg, I am sorry I (forgot) to mention the finer details. This box runs FreeBSD 4.3-STABLE. I updated it from 4.0 to 4.2 to 4.3 via CVSUP and run mergemaster after every 'make world'. It is a box that I inherited from a former employee. The only difference I made to it is compiling an SMP kernel when I updated it. Since then all I've seen in the output of top (invoked just by typing 'top') is confusion (me confused). Well my guess about the load is as bad as you think - pure guess, because that is about what I used to see when it was running on a single processor. It is also true that the output of 'top' I pasted was slightly modified to fit into my mail Window, only I did not realize it would miss out on some details. Here is an output of 'top -SI' (I'm not modifying it in any way) last pid: 98886; load averages: 0.05, 0.05, 0.02 up 1+20:53:04 07:48:06 64 processes: 2 running, 61 sleeping, 1 zombie CPU states: 1.1% user, 0.0% nice, 3.9% system, 0.2% interrupt, 94.8% idle Mem: 83M Active, 11M Inact, 22M Wired, 6372K Cache, 22M Buf, 488K Free Swap: 350M Total, 39M Used, 311M Free, 11% Inuse PID USERNAME PRI NICE SIZE RES STATE C TIME WCPU CPU COMMAN D 6040 1 8 1.66% 1.66 9 469 squid 28 0 92008K 1168K CPU1 0 88:37 4.73% 1.56% squid 98885 bishop1 2 0 1052K 620K sbwait 1 0:00 0.35% 0.05% popa3 98871 geocarjones 28 0 1052K 580K CPU0 1 0:00 0.00% 0.00% popa3 NB: What would be the cause of a version mismatch, the effects and how do I test for such an anomally? How do I rectify the situation in case I have a version mismatch?
