APAR status
Closed as program error.
Error description
Starting from rsct.core.rmc 3.1.4.4, the rmcd process sets a higher stack size than it needs, in most cases resulting in a running size of approximately 200 MB, compared to previous sizes which at startup were usually at most 10-20 MB. Note that this is only about the daemon's size at startup; the daemon can still grow over time, depending on what size cluster it is supporting, but many customers will never see 200 MB in practice, and do not need that size to be defaulted to.
Local fix
Create the file /var/ct/cfg/mc.mlock with just one line of content as follows: # cat /var/ct/cfg/mc.mlock p,200 # Then restart the RMC subsystem: # /usr/sbin/rsct/bin/rmcctrl -k # /usr/sbin/rsct/bin/rmcctrl -s IMPORTANT: RMC cannot be safely recycled in an SAMP, PowerHA 7.1, or VIOS cluster environment. In these domains you must wait until the next available downtime to recycle, or if a reboot is planned then RMC will start with the smaller memory size after the next boot.
Problem summary
Starting from rsct.core.rmc 3.1.4.4, the rmcd process sets a higher stack size than it needs, usually around 200MB.
Problem conclusion
The rmcd startup size has been corrected to normal.
