Open files issues

[Tom Myny]

Hi Guys,

I'm having this each day:

Jan 15 09:06:03 zeus lmtpunix[1029]: IOERROR: creating quota file
/var/imap/quota/l/user.user1.NEW: Too many open files
Jan 15 09:51:29 zeus lmtpunix[24100]: IOERROR: creating quota file
/var/imap/quota/i/user.user2.NEW: Too many open files
Jan 15 09:51:50 zeus lmtpunix[24100]: IOERROR: opening quota file
/var/imap/quota/f/user.user3: Too many open files
Jan 15 09:52:01 zeus lmtpunix[24100]: IOERROR: opening quota file
/var/imap/quota/i/user.user4: Too many open files
Jan 15 10:34:04 zeus lmtpunix[16510]: IOERROR: creating quota file
/var/imap/quota/w/user.user5.NEW: Too many open files
..

I've tried the following:

---

Check file-max:

cat /proc/sys/fs/file-max

359801

---

Checking ulimit:

ulimit -a
core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
max nice                        (-e) 0
file size               (blocks, -f) unlimited
pending signals                 (-i) unlimited
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) unlimited
max rt priority                 (-r) 0
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) unlimited
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Set ulimit -n 10000 on start-up script -> No effect :(


---

Changed NR_OPEN and NR_FILE in kernel, recompile -> No effect :(

Anybody an idea ?
