[Bug 938669] [NEW] Can not increase MaxClients in cups (Max clients reached, holding new connections...)

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I run a terminalserver under Ubuntu 11.10 (oneiric) and CUPS
1.5.0-8ubuntu6. Unfortunately i get "Max clients reached, holding new
connections..." error.

I try to increase the MaxClients value to 8192 in /etc/cups/cupsd.conf
(and LogLevel to debug) but CUPS reduces this to 1/3 of file descriptor
limit from the system with is by default 1024:

/var/log/cups/error_log 
I [22/Feb/2012:12:02:37 +0100] Using default TempDir of /var/spool/cups/tmp...
I [22/Feb/2012:12:02:37 +0100] MaxClients limited to 1/3 (341) of the file descriptor limit (1024)...
I [22/Feb/2012:12:02:37 +0100] Configured for up to 341 clients.

Also i try to set higher file descriptor limit in /etc/security/limits.conf
root hard nofile 64000
root soft nofile 64000

and also add "session required pam_limits.so" to /etc/pam.d/common-
session but CUPS set still MaxClients to 341.

Ulimit seams to works fine:
root at ts:~# ulimit -n
64000

Before i upgrade to Oneiric i have same configuration on Ubuntu 10.04
Lucid and CUPS 1.4.3-1ubuntu1 with works fine.

This seams to by a similar bug to:

Lets me know if you need some more information.
