I have a Percona XtraDB cluster 5.6 with 3 nodes, however few hours ago it started to log the following error message:
18566 [ERROR] /usr/sbin/mysqld: Sort aborted: Query execution was interrupted
The bootstrap node has crashed and few hours later the other two nodes did crash too.
I have restarted all three nodes but I still getting this error on the log.
I read few threads about this problem but none of them gave me an answer.
I’d increase the sort_buffer_size to 7MB, my disk has plenty space, my Galera is 3.8.
This message are being logged by all three nodes.
Does anyone have an idea of what is happening?
