[Gluster-users] KVM lockups on Gluster 4.1.1

Tue Oct 2 08:59:46 UTC 2018

Recently, in one of the situation, we found that locks were not freed up
due to not getting TCP timeout..

Can you try the option like below and let us know?

`gluster volume set $volname tcp-user-timeout 42`

(ref: https://review.gluster.org/21170/ )

Regards,
Amar
