samba - Jun 1999 - oplock_break: client failure in break - shutting down this smbd.

2.0.4b, RH60 (2.2.6+raid1, non root-raid), accessed from win98/ie5.

Intermittently ie5 takes very long to load an html page from samba; at the
same time it loads another html page ok from another linux/samba1.9.x

At 10:47:34 I click on the html page and it is loaded at 10:48:18.

I cannot reproduce this, it happens randomly. I'm sorry but I cannot give
more
details because it happened 30min ago and now is all ok, I cannot test with
other apps reading from the same server till it happens again :-)

What may be the reason for this?

Thanks.

Dear list!

I'm very confused and it would be very nic, if someone can help me.

I've installed a Sambaserver (2.2.3a) based on SuSE Linux 8.0. Nealy 40 
clients with Windows 98, Windows 2000 or Windows XP Pro are working with 
this Samba. Now my problem:
Sometimes the client are crashing down and i see in /var/log/warn something 
like: oplock_break: client failure in break - shutting down this smbd. 
before they crash.

I've searched Google and so on, but i haven't find an acceptable
solution
for this. But i've seen, thatr a lot people have this problem too.

So, does anyone have an answer or a tip ?!

Thanks in advance.

Michael
