Does SHR grow as well? I know that crmd allocated big enough QB buffer
in shared memory (5 Mb or so), and consumes it until it becomes full,
and all that time both RSS ans SHR grow synchronously. In my tests
(several months ago, with 1.1.8) it took several days to reach that
point on a static cluster.

You may also look to differences in /proc/<pid>/smaps (just with diff)
to see what exactly grows.
