We are running samba 2.2.3a on a number of HP/UX 11.00 servers. Each server has about 200 daemons running. We want to install this samba version on our other (bigger ) fileservers. Some of our customers on the samba 2.2.3a servers are complaining about long delays ( for instance with word, but also with other applications) and that they loose connection to the fileserver. When we scan te logfiles, we found a lot of oplock_breack messages like this : [2002/04/03 13:43:36, 0] ../source/smbd/oplock.c:(758) oplock_break: receive_smb error (Error 0) oplock_break failed for file My Documents/HTCE/Voorstel.doc (dev = 40010001, inode = 36296, file_id = 798). [2002/04/03 13:43:36, 0] ../source/smbd/oplock.c:(843) oplock_break: client failure in break - shutting down this smbd. We find also oplock_break messages on the other servers ( running 2.0.7 ) but this doesn't seem to be the same ( and they don't occure that frequently ). What we see in samba 2.0.7 are messages like : oplock_break: receive_smb timed out after 30 seconds. oplock_break failed for file msword/psis/word97/template/letteruk.dot (dev = 4 0100001, inode = 165895). These messages are also seen on samba 2.2.3a. I've searched the samba mailing list, and found that other people seem to have the same problems, but the only solution I found was turning of oplocks.. This doesn't seem to be a good solution with respect to performance. Question: is this a known problem and is there a fix for it?? If not, how can we help to solve this problem, which seems to get very serious at our side..
