Problem with Sun machines hanging

Thanks to everyone who responded to my inquiry. Bob Cook's response (below)
looks very promising since Sun's analysis of our system also pointed to a
problem with AFS. Our Solaris 2.7 machines are at AFS 3.6 so we'll have to
upgrade them ASAP. Our 2.5.1 machines are at 3.4a version 5.74 and also
display the hanging behavior. Another group I work with run version 5.55 on
their 2.5.1 machines and haven't run into the same problem.

It definitely rings a bell, but it is an AFS bell rather than a Solaris

We reported this to Transarc last year as their problem TR-53970.  It was
(supposedly) identified as

      * Defect 12418

       (Solaris only) This fix corrects a problem that occurred when a
       process attempted to access the proc file system.

and fixed in level afs3.6 2.5.  There was also a fix for afs3.5, but I
know which level it went into, or even if it did.

The "supposedly" above is simply because it's very difficult to determine
it fixed the problem; we could never reliably recreate the problem.  I can
say that we have no confirmed cases of it occurring on a machine running
fixed client.
