We are also getting this from about 2 days ago now and then the entire system comes to a grinding halt:
2015-02-20 12:52:01,787 ERROR RPMSONLINE#JPGAmanda -Execution Exception after starting system process message Internal error. Error persisting business object TPTicket Lock wait timeout exceeded; try restarting transaction
2015-02-20 12:45:30,380 ERROR RPMSONLINE#HarrietAdmin -Execution Exception after starting system process message Internal error. Error adding references to Mandate Lock wait timeout exceeded; try restarting transaction
Please advise if this was ever sorted and if anyone has any IDEA what could possibly be causing this.
Thnx
