[ClusterLabs] [Question] The memory which crmd uses increases at every re-check.

[renayama19661014 at ybb.ne.jp]

Hi All,

This memory increase seems to stop somehow or other at some point in time.
I checked it, but this is like the increase by IPC communication (mmap) of libqb.
Is my opinion right?

Best Regards,
Hideo Yamauchi.
