/var/log/glusterfs/glusterd.log: Unable to acquire lock for [volume-name]

[yang-jintao]

glusterfs version 8.6

/var/log/glusterfs/glusterd.log showed much [glusterd-op-sm.c:3940:glusterd_op_ac_lock] 0-management: Unable to acquire lock for vol_xxxxxxx.

Then I stoped gluster-exporter service, glusterd.log returned to normal.

That's mean gluster-exporter make lock conflict?And how to resolve it ?
