Here is the strace command and the output of the FileLog trace, thanks
for your help. I did a "rmdir try" and the strace command complained
"No such device", if I "fs flushvolume" on the client it shows the
directory got removed else it shows it still there.
Output from the "strace -tt rmdir try" command on the client host IP
152.2.140.200:
14:25:39.851544 rmdir("try") = -1 ENODEV (No such device)
I'm not sure why you get an ENODEV, but for the moment I'm ignoring it
to look at the delay problem instead... if anyone else has an intuition
on that, feel free.
Here is the file server log "kill TSTP" 4 times during the same time,
the client IP is 152.2.140.200
Trimming this down to the relevant thread...

So, 152.2.140.115 looks like it's having trouble receiving callback
breaks. Do you know what that host is? Does it perchance have some kind
of firewall or anything that could prevent it from receiving incoming
UDP packets on port 7001?
Hmmm, 152.2.140.115 is my Windows 7 desktop, I use an ssh Secure CRT
client to ssh from 152.2.140.115 to the various linux servers like
152.2.140.200. I am running the OpenAFS Windows client on my W7
desktop and it seems to work fine, copy, create, delete files. So
I assumed the firewall was open, I just did
"rxdebug 152.2.140.115 7001 -version" from the file server and
it hung. I will look into opening the firewall.
I would think that this would not matter since I am ssh'ing from
my 152.2.140.115 W7 machine to linux clients and they are having the problem.
I just logged into my linux desktop 152.2.140.200 and did a
mkdirt and got the delay problem, it is running openafs 1.4.12. From the
file server that I am accessing to the client having issues
rxdebug shows port 7001 is open:
% rxdebug lark.cs.unc.edu 7001 -version
Trying 152.2.140.200 (port 7001):
AFS version: OpenAFS 1.4.12 built 2010-03-17
