Debian, limits and pam

[Adam Majer <adamm@zombino.com>]

Hi all,

I'm sure someone here runs vserver and came across this problem in the
past. Basically, every root logins (from remote or cron), auth.log gets
the following message,

Aug 14 10:59:56 mail sshd[31167]: (pam_unix) session opened for user
root by root(
uid=0)
Aug 14 10:59:56 mail pam_limits[31167]: setrlimit limit #11 to soft=-1,
hard=-1 fa
iled: Operation not permitted; uid=0 euid=0
Aug 14 10:59:56 mail pam_limits[31167]: setrlimit limit #12 to soft=-1,
hard=-1 fa
iled: Operation not permitted; uid=0 euid=0


And of course it is not unlimited, but,

POSIX message queues     (bytes, -q) 819200
pending signals                 (-i) 8191

(limited by vserver itself)


*BUT* I have in /etc/security/limits.conf


*               soft    sigpending      2179
*               hard    sigpending      5375
*               soft    msgqueue        819200
*               hard    msgqueue        819200

and /etc/pam.d/{cron,su,ssh} all have,

session    required     pam_limits.so


So what is going on here? Why is pam or something trying to set these
limits as MORE than in the config files?


I *did* not have these messages until I rebooted the vserver machine.
Now I'm getting these *only* in one vserver.
