--- Comment #31 from Artem Russakovskii <archon810 at gmail.com> ---
I upgraded the node that was crashing to 5.5 yesterday. Today, it got another
crash. This is a 1x4 replicate cluster, you can find the config mentioned in my
previous reports, and Amar should have it as well. Here's the log:

==> mnt-<SNIP>_data1.log <==
The message "I [MSGID: 108031] [afr-common.c:2543:afr_local_discovery_cbk]
