Hello List, I'm trying to diagnose a persistent problem since I upgraded an old Mac from 10.5 to 10.6 and installed the latest OpenAFS.
Essentially what happens is that when the Kerberos ticket expires, there's a limited time (seconds to minutes) during which I can renew both the Kerberos ticket and the AFS token. If that time elapses, the system hangs and I have to hard power-cycle the machine. The particular way in which the system hangs is peculiar. Essentially, all existing processes run fine, but if I try to invoke a new one (including kinit, top, lsof), it hangs indefinitely. Moreover, existing processes that use network resources (e.g. a browser) can't make subsequent network calls, even though connections which are currently open (e.g. MP3 streaming) continue, but won't start again unless they're stopped. Finally, when I try to close the programs using either the AFS filesystem or network sockets, they can't even be killed with a -9. The only recourse is to pull the plug. The reboot, shutdown, or init commands don't even work. The only other time I have seen something like this is on an OpenBSD system with an NFS mount that goes away with a file handle open, or when something has exhausted the user's quota of open file handles. Has anybody seen anything like this before? How would I go about diagnosing it when the wherewithal to do so is crippled itself?
