pam_limits and OpenSSH

[Ognyan Kulev]

Hi,

I have an account server with many users.  It uses pam_limits module to 
limit memory usage etc.  The problem is that sometimes SSH rejects 
connection after the password is entered.  In syslog it prints something 
like "fork: Resource temporary unavailable".  After killing some root 
processes it works perfectly.

Perhaps the daemon first sets process limits and then switches to the 
user and/or fork().  But fork() cannot succeed because there is a 
process number limit to 40 that is applied to root.  This is my 
hypothesis.  I didn't look at sources.  What you think about all this? 
Do you need more information?  I use Debian GNU/Linux potato and OpenSSH 
1.2.3-9.3.

Regards
