Hi Ulrich,
thank you for your answer,
what about which limits do you talk?
The pacemaker software runs by root user, so limits should be increased for
root.
There is output from one of my server:
-bash-4.1# id
uid=0(root) gid=0(root) groups=0(root)
-bash-4.1# ulimit -a
core file size (blocks, -c) 0
data seg size (kbytes, -d) unlimited
scheduling priority (-e) 0
file size (blocks, -f) unlimited
pending signals (-i) 124801
max locked memory (kbytes, -l) 64
max memory size (kbytes, -m) unlimited
open files (-n) 4096
pipe size (512 bytes, -p) 8
POSIX message queues (bytes, -q) 819200
real-time priority (-r) 0
stack size (kbytes, -s) 10240
cpu time (seconds, -t) unlimited
max user processes (-u) 124801
virtual memory (kbytes, -v) unlimited
file locks (-x) unlimited
-bash-4.1# ps -ef |grep pacemaker

With settings in pacemaker or system can be changed for start heavy
application ( java ) at the same time?
