Description Wim Karolat 2007-09-25 02:48:18 UTC
The problem occures on samba 3.2.20a aus well as on samba 3.2.26a
(Eventually on any other 3.2.x release)

We found that some connections timed out when more than
4 clients used the same directory simultaneous  

For repoducing the problem I did the following:
I tested the smbd with 

./smbtorture //server/test -U xxx -N 4 TORTURE

Everything went fine

./smbtorture //server/test -U xxx -N 5 TORTURE

The result was

5 clients started
tdis failed (Call timed out: server did not respond after 120000 milliseconds)
tdis failed (Call timed out: server did not respond after 120000 milliseconds)

TORTURE took 133.370902 secs

After setting the log level of smbd to 5 (it must be 5!!!) everything works fine
even with 20 and more? clients.

Might there be a sychronisation-problem on Solaris 10, I did not find the
behavior on Linux.
(I tested with the Solaris sfw-relase, the last release from sunfreeware and
the last 3.2.26a release I compiled myself with the Solaris cc)

I did the test on the following (SMP)-Machines:

SunOS xxxx 5.10 Generic_118833-36 sun4u sparc SUNW,Sun-Fire-280R
SunOS xxxx 5.10 Generic_125100-10 sun4v sparc SUNW,Sun-Fire-T200

Any ideas?

Best Regards

Assuming you're talking about 3.0.26 and not 3.2.26 (we're not there yet), the only way to reliably diagnose this is to truss the parent smbd with the option to follow its children and drive it into failure.

BTW, do you happen to re-export an NFS import? If so, please retry with a local drive.

sorry for the confusion,
I mentioned indeed 3.0.20a and 3.0.26.a.

In both cases I exported a local filesystem.

I'll setup a truss.

Best Regards

no feedback for more that a year, so I'm closing this one.
