[OpenAFS] advice on troubleshooting blocked cache manager on MacOS?

[Adam Megacz]

Hi, lately I've been encountering a lot of situations where a process
seems to block for a really long time trying to access something in
/afs; it usually succeeds, but only after several minutes.  This seems
to happen only on MacOS (1.4.11, although I saw it with 1.4.10 too).

Can anybody give me some advice on how to go about discovering exactly
which file access is blocked, and perhaps why?  I have control of the
fileserver in this situation.

Thanks!
