xserv cpu flatlining

[bryan taylor]

I came across a xserv today that has been sitting at 100% cpu utilisation after being upgraded to 10.2.6, it has few services running and top shows only two servermanagerd processes at the top of the tree. It was upgraded 25 days ago and has flatlined at 100% since then. Its just used for file serving and users don’t notice any degradation in performance…

any help appreciated

cheers

what does output from top -u look like?

top -u shows MacintoshManagementServer sitting at 85% of cpu usage, I’ve advised them that unles they have OS9 or less on any of their clients that Macintosh manager may not be necessary (would that be viewed as correct advice?)

I would think so. You should always turn off all services you don’t need anyways.
I’ve had a scenario where serversettingsd would do this. I checked the disk (permissions and all) and jjust killed it and it hasn’t happened again.

I have just installed an Xserve for the first time, running 10.2.6 and was very surprised to see the 100% flatline. My top -u readout shows

CPU usage: 82.5% user, 17.5% sys, 0.0% idle
SecurityAg 94.9% , top 2.9%, kernel_tas 1.9%

This is while I’m logged out of the server. Once I physically log in the server cpu readout drops to normal.

Could it be that the server switches cpu loads, acquiring all free cycles for itself?
