The operating system is linux, SuSE 6.4 distribution, kernel 2.2.14 (but it also appeared with the old
version 6.2 and Kernel 2.2.?) I used the sources from the samba site, dated on November ~11th (directly
after the information about the new release came across this list.) As I think it was not available as
bindist, i suppose I have compiled it myself with gcc and glibc2. (I have to do some research about the
version, because we just have run a server update).

The system runs on a dual PIII system with a mylex raid controller and two ethernet interfaces, serving
around 50 clients as login- wins- and fileserver.

The problem occurrs if
* there are find processes on the hdd (understandeable)
* someone publishes a big Frontpage web located on the server (also understandeable)

+++ but also in situations where everything seems to be idle  +++

(even if it is not too fine that the shares get problems while some finds run)
Situation:
Netscape tries to write it$ history file on the server, but this operation fails. Then no network drives
are available anymore. I am monitoring the server, but nothing is going on Processes, etc. and the
workstation and the server are connected via 100 MB, both located on the same TP switch (and there also
seems not to bee too much traffic.

In another special segment of the network the fail rate increases, but this might because they hace to
acces the server via an 10 MB router with sometimes heavy traffic, I suppose.

I could imagine this problem is related to some kind of timeouts, but I am not sure. The question is: if
the connection is broken and I try to open it via the explorer, why does it need such a long time to
reopen it.

I just checked it, this message apppeared in several logfiles, nearly all 2 to 10 minutes (during office
hours, of course), but it isn't that there would be a server-crash, the possibility that there are two or
more exits at the same is estimated < 1%.

On the old server with 2.0.5 the problem didn't exist (there only were the exit codes 406 and 431).

Enough? If you need some more logs, config files or anything else, please ask for them
