There is one LOCK request and one LOCK reply with the NLM DENIED GRACE PERIOD error. Does this say anything? This is still under 2.6.16, I'm planning to upgrade on Friday, unless the problem can be solved with the current version. Besides, is it possible to turn on logging? Also, I've seen the following messages in the kernel log: "do_vfs_lock: VFS is out of sync with lock manager!" This happened only when I dumped the traffic the last time, not within the day, when I tried many times (the logs were not rotated). Any ideas?
