Hi,
We’re using the activiti engine 5.12 in a webapp (already in a production environment) with Spring and MySQL and it always worked well.
Now, the application has a awkward behavior. After calling any method of activiti API we’re getting an HTTP 503 error code in browser, like when we start a new process:
ProcessInstance pi = runtimeService.startProcessInstanceByKey(ProcessInstanceKey, hash);
This startProcessInstanceByKey call never return or gives an exception.
I’m debugging activiti source code, and I can see that startProcessInstanceByKey @ RuntimeServiceImpl.java is called and them it goes into LogInterceptor and SpringTransactionInterceptor, however I’ve a couple of breakpoints on createProcessInstance/2 @ ProcessDefinitionEntity.java and execute/1 @ StartProcessInstanceCmd.java that are never reached.
The activiti configuration is the following:
