I have a opensuse 11 64 bit server with some issues I'm not sure how to solve. I'm getting hundreds of these in the porocess list:

Generally over 300 or so over a couple of days, the load averages can get as high as 300 or so BUT the server is still responsive ~ I suspect the load averages are being reported incorrectly for some reason. I know the only way to get rid of these processes is to reboot, but I'm trying to figure out how to prevent them from appearing. I've disabled the smartd daemon, I've unmounted the /dev/sdb partition. I don't know what's calling the udisk helper...

any thoughts on how to track this down and prevent it from happening?

[BTW - I have tested the disk manually, it is fine - not failing.]

Sounds like a bug. See the following thread:

Usualy this is a problem related a hardware resource that the process is trying to access, maybe can be a driver/module related to the disk controller or its firmware version. Try to check some bugs/issues are reported for your hw

While I cannot add anything to your main problem, I would like to note that the load average is not, in fact, incorrect. Load is defined as the average number of processes waiting for resources (not necessarily CPU), and each process in "D" state counts as one toward the machine's load.
