[Gluster-users] Glusterfs brick logs after upgrading from 3.6 to 3.8

[Only Maybe]

I upgraded my glusterfs (2xreplia) to 3.8.14 from 3.6 yesterday
Then it is producing lots of logs in /var/log/glusterfs/bricks like this:


[2017-08-17 07:28:38.477730] W [dict.c:1223:dict_foreach_match]
(-->/usr/local/lib/libglusterfs.so.0(dict_foreach_match+0x5c)

-->/usr/local/lib/glusterfs/3.8.14/xlator/features/index.so(+0x6da0)

[0x7f2eae49892f] ) 0-dict: dict|match|action is NULL [Invalid argument]

It's eating my disk, about 10G per day. What should I do now?
Thank you very much
