We submitted bug 3342 on Dec. 20th, Too many open files. It has not moved from the new state. So lets try here. We have Dell Quad Xeon server that we end up rebooting about every 2-3 weeks when the number of open samba files sky rockets. The system is a ClearCase server system. We have been monitoring this system for a few months now and are not able to pin down a cause to this issue. The system keeps a pretty constant number of samba open files until what ever triggers the issue and then the number of file opens climbs at a steep exponential rate. RedHat Advanced Server 3 update 3 Linux quinault 2.4.21-27.0.2.ELsmp #1 SMP Wed Jan 12 23:35:44 EST 2005 i686 i686 i386 GNU/Linux Samba version=3.0.6-2E Clients for the most part are Windows XP and Windows 2003 Enterprise servers. Still looking clues as to what might be a cause for this behavior. Our systems people have monitored everything they can think of to see if we can find a correlation but so far nothing has turned up. It is a large, 200+ development environment with NFS and NAS CX400, storage units on the servers. It is a heavy file access, large builds parallel builds on multiple architectures.

Why not try increasing it? You might not be seeing a bug, just a nasty spike in traffic caused by your applications.

There were a lot of bug fixes after that release. I would start with version 3.0.14a. I've been using that version with ClearCase (although with Solaris 8). I would not use 3.0.20anything or even the latest 3.0.21b. It might be useful to see your smb.conf as well as your client MVFS settings. However, ClearCase is not within the scope of this mailing list. David> Clients for the most part are Windows XP and Windows 2003 David> Enterprise servers.

Have you looked for solutions from the ClearCase end? It might also be worth updating your RHEL system -- I think update 3 is rather behind the times now.
