similar to: more smbd CPU mystery

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

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

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 have a reproducible intermittent error large site - "The specified network name is no longer available". This happens when copying large files. Below is part of log level 10 output & strace. Sorry for the long posting. I will probably need to put the loglevel 10 attached to a bugzilla - but thought I would try the lists initially. RHEL4 samba-3.0.25b-1.el4_6.4

I recently got the problem that my smbd process takes up a lot of CPU (about 60%). It's running this high even if I don't access the server through my samba clients. I have tried restarting samba, rebooting the computer and I have been looking at several logs but I can't see what's wrong. It never seems to relax. I need to fix this as fast as possible because my CPU fan is running

Hi all, Our system has just recently begun experiencing smbd processes comsuming enormous amounts of cpu time. I am totally unsure of the cause of this. We are using samba version 2.0.0 (packaged for debian linux). seldon:~$ /usr/sbin/smbd -h Usage: /usr/sbin/smbd [-D] [-p port] [-d debuglevel] [-l log basename] [-s services file] Version 2.0.0 We have not recently upgraded the samba

I've got two WinXP SP2 users. Roaming profiles. One of them takes about 25 seconds to log out unless she has made pretty drastic changes to her profile (My Documents, etc). My second user takes upwards of 3 minutes to log out, even if he has just logged in, not opened a thing or made changes, and then logged back out. Below is part of a strace as I don't know what I'm looking

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

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

The latest version that Western Digital has shipped with the My cloud devices accesses the disk about twice a minute. The access to /dev/sda2 is causing the system to keep the disk from going into standby mode. I don't understand the call to quotactl every minute when no one is trying to access the share. An strace of one of the processes shows the following: poll([{fd=13,

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

We have experienced some trouble with samba lately. The servers load going from 5 to 20 causing everything to go very slow, but when I use top to check which process could be the cause of the trouble nothing uses CPU cycles. We have about 90% idle CPU usage, but load from 5-20. When I kill samba (service smb stop) the root-smb process still hangs and when I kill it (kill -9) the load goes

Hello. I've tried to implement dovecot's deliver LDA to my home mailserver. I've run into troubles :) dovecot-deliver.conf: -- snip -- mail = maildir:%h/Maildir:INBOX=maildir:%h/Maildir mbox_read_locks = flock mbox_write_locks = flock -- snip -- when i run: deliver -d bfg < email.txt dovecot delivers message to ~/Maildir/maildir/new It acctually creates "maildir"

We're running samba-2.2.3a-6 from the redhat 7.3 distribution. Periodically we see a massive load on our server which then quickly goes away. I've spent some time trying to diagnose where the problem is and it appears to be caused by every smb process on the machine (all 360 of them) re-reading the config file at the same moment. THe problem is I cannot see why this should happen and

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
