It’s probably https://bugzilla.redhat.com/show_bug.cgi?id=1593826 <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.

The version of glusterfs I installed is 3.12.8, and I find it`s client also consume huge memory.
[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?

Hi,

Please take statedumps of the 3.12.13 client process at intervals when the
memory is increasing and send those across.
We will also need the gluster volume info for the volume int question.

Thanks,
Nithya

Thanks for your reply, I also test gluster 3.12.13 and found the client
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
180095 root 20 0 4752256 4.091g 4084 S 43.5 1.6 17:54.70
glusterfs
I 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?

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
[mount/fuse.fuse - usage-type gf_fuse_mt_iov_base memusage]
49805 size=4250821416
49806 num_allocs=1

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.
