My mail server is configured with :
   kernel-2.4.19
   grsecurity-1.9.6   ---> with  CONFIG_GRKERNSEC_EXECVE=y
   iptables-1.2.7a
   postfix-2.0.9
   courier-imap-1.7.1 ---> with  maxprocs=6

and /etc/security/limits.conf have :
   * hard nproc 50

Can't understand why get :
   grsec: Attempt to overstep process limit by imaplogin (couriertcpd)

in this situation:

 - booting server
 - some other server procs start (ftpd, named, ntpd, etc...)
 - connect to couriertcpd from a mozilla client
       --> 1st try --> Ok, can see accounts' mail
      (10 new procs start on server having 5 imap accounts)
 - close mozilla client
      (10 procs end)
 - connect to couriertcpd from a mozilla client
       --> 2nd try --> grsec: Attempt....

How can overstep process limit ?

Seems to me that the process counter isn't reset when I close imap client

Any suggest is welcome
thanks in advance

Lucio
