Re: [Samba] Samba shares freezing
Jermey, Will work on getting a trace back with gdb. I'm now seeing in the log files for clients this error: [2010/01/21 09:19:01, 0] smbd/oplock.c:317(oplock_timeout_handler) Oplock break failed for file mozilla/thunderbird/pluginreg.dat -- replying anyway What's strange is this error only occurs with our terminal servers, where we have multiple users logged in. All other single clients do not show this error at all? And it is with our terminal server users that are seeing the most problems with the shares freezing up or acting very slow.

[Samba] Samba shares freezing
All, Looking for some help here. Not finding anything on the net that looks the same as what I'm seeing. Running Solaris 10 Sparc, on a Sunfire 5220, 16Gb of RAM. Samba version 3.4.5 and using ZFS file systems with user quotas. All cifs clients shares to this server freeze after about 10 to 15 minutes of connectivity. Only fix is to restart samba. I'm not getting any errors from samba or on the /var/adm/messages or /var/log/syslog files. Totally stumped here. This freezing also happened with 3.4.0.

Can you attach to a frozen smbd with truss to see where it might be stuck. Or alternatively ensure you are built with symbols, attach to the frozen process with gdb and get a backtrace using the bt command.

Re: [Samba] Samba shares freezing
Hey, if you are using Solaris 10, not openSol, you might want to look at this page. We are using it here at a hospital with some 2k users (probably a lot less than you, but...) and it's working very well. http://www.nineproductions.com/technology/1-sun-solaris/3-solaris-10-samba-zfs-configuration.html One of the things we had major problems with was not having oplocks. As I recall, they are pretty useful. we have kernel oplocks=yes, oplocks=yes, but use a fair amount of vetos. This serves as a fileserver for everyone's My Documents folder. However, we don't use roaming profiles, so that's probably a blessing on our side there. Hopefully that link helps you as much as it did us. CJ Keist wrote: All, Looking for some help here.
