2.0.7: unsolicited oplock break reply

I've used
oplocks = no
for a long time now, because of the famous "oplock_break" error, but I
decided to give 2.0.7 a try.

I still get "oplock break" errors as before, but this time I got a new
error too:

Note that:
- the server is linux 2.2.14/samba2.0.7; it's not the server where I
used to made oplock_break tests. It's another one on another lan. It's
used almost exclusively to store an MSMail PostOffice and personal
mailbox (pst) files (Outlook97/98/2000 of 15/20 users point to it). 
- the client machines are all win9x.

... I know MSMail is bad, but it's not my choice :-))

Things would almost certainly get better if you switched those
over to IMAP4, which current Outlook Express and (I think!)
Outlook both support.  We have people here using Outlook and
Unix machines for EMAIL storage, but they're using POP/IMAP
for folder and message access, not Samba.

Old adage of mine...if you have a choice between client-server
and file access, pick client-server!

2.0.7: unsolicited oplock break reply

Hello,

At 05.26 04/05/00 +1000, you wrote:>I've used

I'm almost sure it's a client problem. We had similar problems with a 
customer and turned out it was a buggy hardware lpr print server (Ricoh in 
that case, but most of them are buggy) wich every now and then stopped 
responding to lpq request. Every client connected to that printer, either 
through Samba or directly, stopped responding to anything, even pings, not 
only oplock break requests, until lpq timeout. Some of the clients have 
been reinstalled from scratch just to track where the problems was.
         You know, Win95/98 have a special kind of multitask kernel which 
is able to do no more than *one* task at a time. Anything connected to a 
Win95/98 client that doesn't respond in a timely fashion could lead to this 
kind of problems.

Bye!
