Hi Volker Unfortunately I didn't keep this information but fd=14 now (samba pids) points to [PRO] [root at pf3il0024 ~]# for i in `ps -ef | grep smbd| grep -v grep| awk '{print $2}'`; do ls -la /proc/$i/fd/14; done lrwx------ 1 root root 64 Feb 10 21:16 /proc/3238/fd/14 -> /var/lib/samba/locking.tdb lrwx------ 1 root root 64 Feb 1 01:33 /proc/18405/fd/14 -> /var/lib/samba/locking.tdb lrwx------ 1 r...

Hi Volker Finally I loaded the following configuration in our test environment [global] deadtime = 60 keepalive = 10 [dossiers] locking = Yes ; If yes, turns on byte-range locks. strict locking = No ; If yes, denies access to an entire file if a byte-range lock exists in it. ; posix locking = Yes posix locking = No

Hi Volker and the list Yesterday the problem appeared again I could launch a strace command over a samba PID to see what was going on and this is the result [PRO] [root at pf3il0024 ~]# strace -frp 57686 Process 57686 attached - interrupt to quit 0.000000 fcntl(14, F_SETLKW, {type=F_RDLCK, whence=SEEK_SET, start=35824, len=1} It seems the process was trying to get a read-lock but no one answers I don't know where to find out more information about this issue Any ot...

...gt;If it is in D state (according to ps u), it sits in the >kernel. If not, you could try stracing the process (strace >-ttT -p <pid>) and see what it does. gstack <pid> also helps >often. We got the following strace over the samba process 'locked' *[PRO]* [root at pf3il0024 ~]# strace -p *38063* Process 38063 attached - interrupt to quit fcntl(39, F_SETSIG, 0x23) = 0 fcntl(39, F_SETLEASE, F_WRLCK) = 0 getxattr("tf-PRENSA_DIRLOG_20141202_100852", "system.posix_acl_access", 0x7fff5f0b8320, 132) = -1 *ENOENT* (No such file o...
