Планировщик Quartz с кластером percona db, выдающим ошибки взаимоблокировки

Привет. Мы пытаемся настроить кварцевый планировщик в кластерном режиме с многоузловым кластером percona (master-master galera). Tocmat запускается и работает, но часто видит нижеприведенное исключение в журнале.

Любые указатели?

Tomcat 7.0.54 Quartz - 2.1.7 Кластер Percona XtraDB 5.5
