Seems like it only happens during or after SST. I wonder if this may happen because of data inconsistency... On Thu, Dec 22, 2016 at 2:27 PM, Vladislav Vaintroub <vvaintroub@gmail.com> wrote:

I run this query every minute and I have this exception after couple of hours... Class.forName("org.mariadb.jdbc.Driver"); conn = DriverManager.getConnection(DB_URL, USER, PASS); stmt = conn.createStatement(); String sql = "SHOW STATUS LIKE 'wsrep_%'"; rs = stmt.executeQuery(sql);
Is there something i can do to get root cause of that exception? Thank you, vic
It should be some something on the server, but I do not have a better idea that to look in server's error log file. Maybe periodic "show processlist" can also sched some light on what happens right before server would close the connection. As I mentioned, error log seems to indicate memory pressure of some sort.
