If I just mount the client,I the memory will not rise. But when I read and write a lot of files(billions), the client will consume huge memory. You can check it in this way.

I’m not seeing any leaks myself, been on 3.12.13 for about 38 hours now, still small.You did restart that node, or at least put it into maintenance (if it’s ovirt) to be sure you restarted the glusterfs processes after updating? That’s a lot of run time unless it’s really busy, so figured I’d check.

Thanks for your reply, I also test gluster 3.12.13 and found the client also consumes huge memory:PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND180095 root 20 0 4752256 4.091g 4084 S 43.5 1.6 17:54.70 glusterfsI read and write some files on the gluster fuse client, the client consume 4g memory and it keeps arising.Does it really fixed in 3.12.13?It’s probably https://bugzilla.redhat.com/show_bug.cgi?id=1593826, although I did not encounter it in 3.12.8, only 3.12.9 - 12.It’s fixed in 3.12.13.

To: gluster-users@xxxxxxxxxxx_______________________________________________The version of glusterfs I installed is 3.12.8, and I find it`s client also consume huge memory.
I dumped the statedump file, and I found the size of a variable is extreamly huge like below:
[mount/fuse.fuse - usage-type gf_fuse_mt_iov_base memusage]
49805 size=4250821416
49806 num_allocs=1
49807 max_size=4294960048
49808 max_num_allocs=3
49809 total_allocs=12330719
Is it means a memory leak exist in glusterfs client?
