When running the fileserver with -auditlog the output is:
Wed Aug 11 16:27:25 2010 [4] EVENT AFS_SRX_SetLock CODE 0 NAME ...
...
there are no lines with CODE not 0.

fstrace on the client for a process with an error executing flock
shows the following lines:

(I added a "sleep(1)" when the flock is in error)

Shall I add some afs_Trace calls to the code?
