I'm working on an oddball problem at work and thought maybe someone might have seen something similar. Situation: Recently installed an XServe and have started moving everybody's data over to it. A little slower than running locally, but a whole heck of a lot easier to manage/share/back up. Problem: One computer, and only one, has been freezing about twice a day. And, of course, it's the boss'. Everything seems to be identical to the rest of the computers, yet his is the only one freezing. Symptoms: Appears to be going into the state that OSX occasionally does when a mounted disk isn't responding but the OS doesn't just remove it; applications begin to stick on the SBOD one after another until the entire machine is stalled. Soft-restart attempts generally fail as does force quitting. The computer was fine before the minor workflow change, a wreck after. During these episodes the server is, apparently, still mounted and accessable--the one time I witnesed a freeze I could browse it until the Finder died too. The logfiles don't show anything interesting that I noticed. The only differences I can come up with is that the computer is a quicksilver, unlike most of the others, and that he runs Classic frequently (still uses a HYPERCARD STACK for his address book--change-averse, shall we say), but he insists Classic isn't always open when the stalls occurr, though it's still my prime suspect. Has anybody else seen issues like this? Any suggestions of what to check?
