Hi, this is an old problem it was worse in the pre-3.5.0 releases, on solaris 10 all the cpu gets consumed by fcntl calls: 7963: fcntl(22, F_SETLKW64, 0xFFBFE050) = 0 7963: fcntl(22, F_SETLKW64, 0xFFBFDE78) = 0 7963: fcntl(22, F_SETLKW64, 0xFFBFDF58) = 0 7963: fcntl(22, F_SETLKW64, 0xFFBFDF70) = 0 7963: fcntl(22, F_SETLKW64, 0xFFBFE050) = 0 7963: fcntl(22, F_SETLKW64...

Hi, I am still struggling with the printing in a AD2008 R2 environment I changed to 3.2.15 by now. Still very slow, I am running on solaris 10. Not sure if my clients are so chatty by now but it is really killing any performance. Using truss I see loads of: 19702: fcntl(17, F_SETLKW64, 0xFFBFE640) = 0 19702: fcntl(17, F_SETLKW64, 0xFFBFE150) = 0 19702: fcntl(17, F_SETLKW64, 0xFFBFE218) = 0 19702: fcntl(17, F_SETLKW64, 0xFFBFE578) = 0 19702: fcntl(17, F_SETLKW64, 0xFFBFE640) = 0 19702: fcntl(17, F_SETLKW64...

Hello, I've come across a curious issue with Samba 3.6.10. When running 'emacs' version GNU Emacs 23.3.1 (i386-mingw-nt6.0.6002) of 2011-03-10 on 3249CTO on Windows Server 2008 SP2 x64 and issuing a file "revert" of one sort or another against a Samba-served file, the 'smbd' process leaks two or three handles. Eventually, when 16k handles are open, this causes

We have a Linux file server for a set of computer science and engineering labs where each lab contains machines running Mac OS X, Ubuntu Linux, or some incarnation of Windows. At times the these machines become almost unusable and I think I have narrowed the problem to smbd processes soaking up all the CPU on the server. Running 'top' on the server reveals a dozen or so entries like

Hi! I'm currently hunting a strange problem and looking for help! I have a samba3 fileserver (currently samba-3.0.20b, but problem can be reproduced with samba-3.0.7, but _not_ with samba2 like 2.2.8a), and I see performance problems when writing files with MS word 2002 SP3 from a NT4.0 (SP6a) workstation.
