[Pacemaker] nofile limit with pacemaker

[Daniel Jung]

Hi all,

I came across a problem with no file limit for one of the 
primitives(slapd) running in pacemaker. To verify that this is result of 
running in pacemaker,  i put the node in standby and start up Slapd 
manually, the nofile limit is shown as bound by 
/etc/security/limits.conf. However, if i online the node and let slapd 
start up through pacemaker, the limits seems to be inherited from 
pacemaker (as it should from forking) but with values that are not set 
in the limits.conf.

I didnt see any ulimit setting in init file. I was wondering if the 
pacemaker was compiled with set fd_setsize? Is there a way for pacemaker 
to  accept limits.conf setting instead of recompiling?

Thank you for help.
