[Gluster-devel] glusterfsd memory leak issue found after enable ssl

[Zhou, Cynthia (NSB - CN/Hangzhou)]

Hi,
In my recent test, I found that there are very severe glusterfsd memory leak when enable socket ssl option.
If I monitor glusterfsd process RSS with command:  pidstat -r -p <glusterfsd pid> 1
And at the same tme, execute command: gluster v heal <volume> info, i find that the RSS keep increasing until system Out of memory.
I have tried even with latest glusterfs5.5 version, this issue still exists,
Have you any idea about this issue?

The config in my env:
