Hi and thank you Gaurav,
I will send the info about RAM to our Unix team... as for the output you asked for:
we do not seem to have an init.d in the path you specified.
xx2:/etc/rc.d # ll i*
-rwxr-xr-x 1 root root 14041 May 24 2013 ipmi
-rwxr-xr-x 1 root root 2290 May 11 2013 ipmievd
-rwxr-xr-x 1 root root 3002 May 11 2013 irq_balancer
-rwxr-xr-x 1 root root 4275 Nov 8 2010 ivman
xx2:/etc/rc.d #
and for ulimit
xx2:/etc/rc.d # ulimit

Thank you again!
