I have set up my glusterfs cluster as Striped-Replicated on GCP Servers, but I am facing memory leak issue with Glusterfs fuse client. Its memory consumption is increasing every day.

Both glusterfs server and glusterfs fuse client is using the latest version(Client-4.1.5, Server- 4.1), but the below process is consuming high memory on the client servers.

glusterfs --fopen-keep-cache=off --volfile-server=gluster1 --volfile-id=/+ 

Every day I can see that memory consumption of the above process is increasing, a temporary fix is to unmount and kill the process.

In my glusterfs client server, I am getting 'Stale File Handle error'. Not sure this error caused the memory leak.

Also, my glusterfs server is using default settings. Please help if there is any patches or fix.
