Hey guys,I'm really confused by this error :
org.activiti.engine.ActivitiOptimisticLockingException: JobEntity [id=132558] was updated by another transaction concurrently

I'm using activiti-rest and activiti-explorer. These are stock 5.17.x and we deploy our bpmn20 to these via REST. Our process has an async=true subprocess that contains a timer event and I'm guessing this is where the issue arrises but I'm not sure why? Can someone explain how this could result in concurrent transactions? Is there a way to raise the retry count directly from the process xml?Thanks guys.
