Workflow stops between tasks - cannot restart

[Dart, Jocelyn]

Hi Mike,
It could still be a deadlock race - not at the time the problem originally occurs but when the error is resolved the workflow may be trying to resolve the two outstanding branches of the fork at once.  I suggest you report the fact that if an error in one branch of a fork is resolved and mutliple branches can now continue the workflow stops. That's a completely separate problem to what caused the original error.

Hi Jocelyn,
I've been trawling OSS, all the relevant items are already in the system. Though it's unlikely to be a deadlock issue - the timing is usually hours apart.
Currently this is a bit frustrating as the original error ('branch 1') is happening in prod due to a bug which OSS have been working (I hope) on for 2 months already... so, do I report a bug that manifests itself due to another bug? Was going to get the first problem resolved before reporting this one.
 
Thanks for your input!
Cheers
Mike

In any case this sounds like one for the developers to help fix.  They'll probably want you to do a workflow trace to narrow down where the problem occurs.
