Oracle Linux 6.6 Goal: user jboss_app should be able to run up to 16384 processes
We increased max user processes because a user was running out of processes. Current contents of limits.conf:
#<domain> <type> <item> <value> # #* soft core 0 #* hard rss 10000 #@student hard nproc 20 #@faculty soft nproc 20 #@faculty hard nproc 50 #ftp hard nproc 0 #@student - maxlogins 4 * soft memlock 8388608 * hard memlock 8388608 * soft nofile 16384 * hard nofile 16384 * soft nproc 16384 * hard nproc 16384 # End of file When we log in as jboss_app, and run ulimit -a, we only see 1024 processes. allowed.

EDIT: IN this serverfault question I found there is another file in the RHEL family, /etc/security/limits.d/90-nproc.conf, which is read when the user is accessed vi sudo.
[root@tstjboss05 limits.d]# more 90-nproc.conf # Default limit for number of user's processes to prevent # accidental fork bombs. # See rhbz #432903 for reasoning. * soft nproc 1024 root soft nproc unlimited I edited nproc in this file and got my desired result.
