Comment 10 for bug 1630233

@Rvyalov. The problem is not in Galera. It uses around 500-700MB which is ok. The problem is in services such neutron that uses 100Mb per process, but 16 processes spawned.

Run

ps -C neutron-server -orss= | awk '{ count ++; size += $1 }; END {print "Number of processes =",count; print "Memory usage per process =",size/1024/count, "MB"; print "Total memory usage =", size/1024, "MB"}'

next time to find a victim.
