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

Hi, We have a few users experiencing locking problem. When starting Thunderbird, there is no new emails in Inbox. Dovecot createa a lock file /var/spool/mail/<user>.lock. It never completes openning Inbox. If closing the mail client, the open imap session does not get closed, nor the lock file get deleted. Here are the errors in log: dovecot: Oct 13 11:18:35 Warning: IMAP(user1): Our

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

One of my smbd processes used 100% cpu. I straced the process and the output follows: washington:~# strace -p 3416 fcntl64(13, F_SETLKW64, {type=F_UNLCK, whence=SEEK_SET, start=404, len=1}, 0xbfffefa0) = 0 sendto(12, "\3\0X\r\0\0&\0\0\0\0\0\0\0\'\374\f\0\0\0\0\0\16\0\0\0", 26, 0, {sin_family=AF_INET, sin_port=htons(41373), sin_addr=inet_addr("127.0.0.1")}}, 16) = 26

Hi, A day or so after starting samba, some daemons (diferent forks) begin to hang. Then, the WinXP clients hang too completely. When I try to figure out what is happen, I see that smbd daemons hangs always in a fcntl64() call: # strace -p 6414 Process 6414 attached - interrupt to quit fcntl64(14, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=3684, len=1} <unfinished ...> Process 6414

Hi, Rowland, and thanks for the reply. The PDC OS is Slackware 13. The BDC OS is Slackware 14. The choice to use Samba 4.0 was merely due to its inclusion on the Slackware 14 distro. I'll worry about upgrading that once I have the migration complete. I will post the two machine's respective smb.conf's later today. -- View this message in context:

Well I have determined that everytime someone logs in/logs out of a windows box in our lab *ALL* of the files in "My Directory" are copied from/to the file server to the local client. Needless to say this is retarded and needs to stop. The local sys admin needs to perform some windows voodoo to redirect this directory. Still this brings the mystery as to why smbd would take up so much

Hello together, since today morning I have an massive performance issue with samba 2.0.6-3 (Debian - Testing-Tree) in my samba production environment. Samba responds very slowly within the logon process (2-3 Minutes for each line in the netlogon.cmd). Later during normal operations opening from files works very slowly and often breaks connection. There is no cpu or memory load on the system.

dear all, the following problem occurs periodically (appr. once a week) here: the number of smbd(s) will dramatically rise (up to 500 and more...) when having a look what the proccesses are doing i only see that they are waiting for getting a lock: fcntl64(4, F_SETLKW64, {type=F_WRLCK, whence=SEEK_SET, start=240, len=1}, 0xbfefa5c0) = 0 filedescriptor 4 is bound to my secrets.tdb ! after that

Gerry, It looks like 3.0.25 breaks "stand alone/no winbind/no domain" servers. This is remeniscent of the 3.0.23b SID/GID problem. The only thing that jumps out at me is that you can't access your home share and other shares just quit working. Looking at the log files, I see this: [2007/05/14 15:24:55, 10] smbd/open.c:share_conflict(389) share_conflict:

I am trying to get a W2K server to trust a samba 3.0 server. I followed the directions in the InterdomainTrusts.html file and receive an error that the domain is not found when trying to trust it. my samba server is configured to use pam to authenticate. I had to add a user named "w2kdomain$" on the machine before I could run smbpasswd -a -i w2kdomain. Once I did that, it created the

Problem - smbpasswd does not seem to be recognizing my "add user script" option to automatically create Unix users when adding a samba user. I am running Samba version 2.2.8a (from source) on a Linux (Redhat 8.0) system.

We've seen Samba crash and burn twice in the last 48 hours - it just started happening, and we have no idea what might be causing it. I'm hoping that someone will recognize this problem. Platform: we are running RedHat Enterprise Server, with Samba 3.0.7. We're using security=domain in an old-style NT4 domain environment. The symptom that we're seeing is that the number of

Hi list, I have a strange permission problem with secrets.tdb on an nfs mounted filesystem.

Hello, I'm using dovecot as a mail relay so that I can back up my providers IMAP mail locally. I'm impressed how easy this was to set up, but I'm having a quirk that I would like help with, if possible. There are many weak links in my set-up chain, if you will, but I think I've narrowed the problem. I'll describe my set-up anyway. I'm running dovecot 1.1.4 on ubuntu

Hi all, I have a problem with samba : I can create files, but can't create directories. The server has many shares, on seperated disks. We consider two of them : one 2Tb share and one share with more than 7Tb. Samba configuration is good, and works on many other servers, and on this one except for the large share. Permissions are correctly setted up too. I can read/write files and

I think I have narrowed down the problem why smbd processes are soaking up so much CPU on our file server. Here are some selected samples from strace output as I attached to the offending smbd process: Culprit #1 I took three sample snapshots, each lasted for several seconds, and I took them minutes apart from each other. I noticed many lines involved stat'ing the a single file in the
