similar to: 3.6.10 file handle leak under ancient 32-bit kernel

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. Saving even the smallest file takes more than 10 seconds! Copying files with Windows

Hi! I need some help. We use samba4 as AD, and now when clients connect to server, samba process stuck at 100% cpu. samba Version: 4.3.4 Release: 13.el6 top: 3777 root 20 0 131m 46m 28m R 99.7 0.3 219:20.53 /usr/local/samba4//sbin/samba -D 24541 csertam 20 0 49260 11m 9048 S 25.1 0.1 0:01.56 smbd -D 7080 squid 20 0 926m 908m 6428 S 9.9 6.2 11:43.50

Did you install it from binary packages ? compiled from source ?

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:

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. Relevant lines from smb.conf: [global] server string=Samba Server netbios name = smbpdc security = user domain logons=yes domain master = yes

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

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

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

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

Im having an issue with what I believe might be pinned down to a need for a proper samba configuration. The problem: sparse writes (not sure which, either write sparse files to a system that doesn't support them, or vice versa) The system: Zfs-on-linux, samba share Accessing system which is erroring: Win7x64_ult, freefilesync Error message NOTHING I have done to it is

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.

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, When are client sessions closed? Let me explain what I'm trying to do... we're in a School district and we try to stop kids logging more than once. They way I did this before was to dump the active sessions from our previous Server2003 fileserver into a file once a minute and process it with a Perl script to check who was connected from where, rebooting machines remotely as

Hi, I'm having problems in a second domain controller machine. Every time a restart samba, few time after a samba process starts using almost 100% cpu. It's a Centos 6.5 x86_64 with the following: sernet-samba-libsmbclient0-4.1.6-7.el6.x86_64 sernet-samba-ad-4.1.6-7.el6.x86_64 sernet-build-key-1.1-4.noarch sernet-samba-libs-4.1.6-7.el6.x86_64 sernet-samba-client-4.1.6-7.el6.x86_64

Hi, Yes, I already thought about it. I have the sernet repo installed.. Is possible to yum update and jump from 4.1.6 to 4.1.14 directly, without problems or should I follow some kind of procedure to avoid future problems? Regards, Bruno Andrade.

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
