I am running MySQL Galera 5.6.27 on a 3 node cluster since about a few weeks now in production. Since going live I found that once in a while I do get MySQL errors that previously did not ocure and where the syntax seems to be OK. Furthermore there is no error number or error message comming with the error.
E.G.:
If I query the db now with this statement, then everything works fine. I therefore assume that this is a Galera specific issue as most of the problemematic queries are updates, or inserts.
How could I track down that problem in order to fix it? Thank you for any help on this.
