Hi all,
We have come across a strange problem with our jbpm process. It contains a fork and a join
at the end. Both branches execute some subprocesses and when they finish, they meet in a
join. Usually after the join, the main execution finishes, but sometimes (very very rarely
- total of 3 cases) the processes wait in the join and the main execution never finishes.
What we can see in the database in the "jbpm4_execution" table, is that the main
process is in an "inactive-concurrent-root" state and the two subprocesses are
in the "inactive-join" state.
Has anybody seen something like that? We are just curious if we are doing something wrong
or is it a rare bug?
There is a workaround for that, just do this:
+executionService.endProcessInstance(pid, state)+
but we would rather not see it in the database at all.
Any help would be appreciated.
We are using JBPM v4.1,
Here is our jbpm process in xml:
