Hi,

I have noticed very strange client hangs running a custom netboot image
that has most parts of /usr in afs. We use this netboot image for
installation and some times programs hangs in wchan afs_cv_wait and this
is the tcpdump of afs traffic:


09:17:15.011804 IP client.afs3-callback > server1.afs3-fileserver:  rx
data fs call fetch-status fid 537185423/4227/29342 (44)
09:17:15.781413 IP server1.afs3-fileserver > client.afs3-callback:  rx
data fs reply fetch-status (148)
09:17:16.801638 IP server1.afs3-fileserver > client.afs3-callback:  rx

09:17:43.172386 IP server1.afs3-fileserver > client.afs3-callback:  rx

09:17:49.342721 IP server2.afs3-fileserver > client.afs3-callback:  rx
data cb call probeuuid afsuuid 005f6ad6da6d14feaa3c82ed5f7daa77 (76)
09:17:49.342812 IP client.afs3-callback > server2.afs3-fileserver:  rx
abort cb reply probeuuid errcode 1 (32)

Has anyone seen/heard of anything similar and what the cause might be?
Has this been fixed/confirmed/noticed?

Regards,
Jerry
