I am really hoping that an update may come out for the below shortly. I have been bitten by this several times in the last week (60% write 40% read) with some pretty complex items going on. I have done what I can to attempt to reduce the frequency of this. I understand that the bug also impacts the newest version as well as the source mysql/MariaDB with the cluster setup.
I do not really want to run a single node with wsrep disabled but I may have to in the near future…
Any updates you can give would be appreciated.
