We scan it use memory-leak tool, there are following prints. We doubt some open ssl lib malloc is is not properly freed by glusterfs code.

I’ve test on glusterfs3.12.15 and glusterfs5.5 all have this issue, after enable tls ssl socket,
when execute gluster v heal <vol-name> info, will trigger glfshel to connect glusterfsd process, and cause glusterfsd process memory leak. Could you please try in your env?

Hi,
In my recent test, I found that there are very severe glusterfsd memory leak when enable socket ssl option
What gluster version are you testing? Would you be able to continue your investigation and share the root cause?
