80M is more than I would expect. One thing I know you can do is lower the IPC buffer size. That can be done in /etc/sysconfig/pacemaker. Set the PCMK_ipc_buffer to something smaller than whatever it defaults to. -- Vossel > > We would like to know if there are any configuration settings or fine tuning > that we need to perform to reduce the memory usage.
