[OpenAFS] fileserver crashes

[John W. Sopko Jr.]

The user that was having the problem upgraded to OpenAFS 1.3.73 and is still
having problems. He goes into his application, (Matlab), which allows you
to cd and list files from within the application. When he does this the
application just hangs. I turned up the FileLog debugging and the
system just streams requests like the following continuously until he kills 
the Matlab application:

He has the same problem from 2 different windows machines running
1.3.73. The directory he is listing does contain 1777 files.
We can see the files fine through a normal Window explorer type window and
I can list the directory from a 1.2.11 linux client without a problem.

I am more of a unix/linux guy but I have involved our windows folks.
If you can tell me how to use the windows debug client or get more 
information some other way I will be happy to try it out.
Thanks for your help.
