I run this query every minute and I have this exception after couple

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,

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.
