Hi Samba community,
Last year we upgraded from version 3.0.10 to 3.0.20b and at the same
time
switch from NT-domain controller membership to AD membership. After this
upgrade we began to experience that drives sometimes were not mapped.
We saw this both on our Citrix servers and on our XP PCs.
A couple of weeks back we then moved to 3.0.21b in the hope that this
misbehaviour would disappear, but in fact it didn't. I noticed that we
see
the error message:
Too many open files
each time drives are not mapped.
In the log files I can see that it has happened even when we ran version
3.0.10.
We run Samba on Solaris and have previously increased both rlim_fd_cur
and
rlim_fd_max to 1024. Do we need to increase these values further ?
If I do plimit smbd process it says:
resourcecurrent maximum
time(seconds)unlimited unlimited
file(blocks) unlimited unlimited
data(kbytes) unlimited unlimited
stack(kbytes) 8192unlimited
coredump(blocks) unlimited unlimited
nofiles(descriptors) 10020 10020
vmemory(kbytes)unlimited unlimited
I have tried increasing nofiles to 20040 without any success :-(
Here are some examples of the full error messages from the logs:
[2005/04/21 08:45:36, 0] passdb/pdb_smbpasswd.c:startsmbfilepwent(204)
startsmbfilepwent_internal: unable to open file
/usr/local/samba/private/smbpasswd. Error was: Too many open files
[2005/04/21 08:45:36, 0]
passdb/pdb_smbpasswd.c:smbpasswd_getsampwnam(1326)
Unable to open passdb database.
another example:
[2006/01/26 08:19:06, 0] lib/debug.c:reopen_logs(591)
Unable to open new log file /usr/local/samba/var/log.pcped250: Too
many open files
Have any of you experienced the same and if yes what did you do to
get Samba to behave ?
It is as if files are not closed...
Any help would be appreciated !
Kind regards, Hans.
