[Warning] WSREP: Send action {(nil), 785, TORDERED} returned -103 (Software caused connection abort)

 

Hi there, I need to ask a guide from here. I have 5 galera cluster using
mariadb 10.1 on centos 7 hosted on VPS for a few month. It running well
until a weeks ago, during my leave, our VPS hosting rebooted our server. I
create a backups and reboot the clusters1 till cluster2 (I don't enable
auto start services on my box). Then on galera cluster 1, I ran command
"galera_new_cluster" and start services on others clusters.

cluster 2 - cluster 5 are working great. But it seems, cluster1 has
problem. I checked services status and I got lot of this message :

Mar 10 15:04:05 galera1 mysqld[6628]: 2017-03-10 15:04:05 139929087744768
[Warning] WSREP: Send action {(nil), 520, TORDERED} returned -103 (Software

I tried to connect mariadb galera on cluster 1, seem the data are not
synced unlike the others 4 cluster. Anyone face the same problem? Any
guideline for me to troubleshoot this problem is most appreciated.
