Public bug reported:
Binary package hint: cupsys
Description: Ubuntu 10.04.1 LTS
Release: 10.04 - Server
64bit System
cups 1.4.3-1ubuntu1.3
------------------------------------------------------------------------------------------------------------------------------------------------------
Hello,
when I print a job or just delete a job, the amount of open files used by cups
increases by ~ 40 - for every job. Although the memory usage goes up. That' s
reproducable. Only a restart - not reload - helps to get cups back to a normal
status.
In the logfiles you only find the message "too many open files". This
message occurs just when it's too late. The server doesn't accept
connections any more. You cannot find any strange messages in the logs
before.
Now, I think it has to do something with samba. Because the files that are
opened on each job and not closed are:
> cupsd 31763 root 683u unix 0xffff88015d559b00 0t0
> 308738831 socket
> cupsd 31763 root 684r CHR 1,9 0t0
> 907 /dev/urandom
> cupsd 31763 root 685u REG 251,3 36864
> 106058 /var/lib/samba/passdb.tdb
> cupsd 31763 root 686u REG 251,3 16384
> 106059 /var/lib/samba/account_policy.tdb
> cupsd 31763 root 687u REG 251,3 77824
> 106057 /var/lib/samba/group_mapping.ldb
> cupsd 31763 root 688u REG 251,3 40960
> 106043 /var/lib/samba/secrets.tdb
They are left on every job that is cancelled or printed - till there are
too much open files.
I do not use samba to print on cups, although amba is installed and
needed.
Because I need to install a print server for thousands of Pages every
day, I need to find a solution for this problem.
Thanks for any help!!
