Rubén Pérez Vázquez commented on MH-8052:
-----------------------------------------
I'm glad that fixed the issue, Greg. However, I think Josh's comment was
correct. It's true that it's a shared folder and other processes not in the
same JVM can access it (which should be another issue to consider), bit, in
this case, it seems obvious that the.collection folder is created by the same
JVM, because each specific job is handled by a single worker (so no other
machine could have created that folder), different workflow sdon't access to
the same folders (so the failing operation *had* to be this workflow's) and
there are no concurrent jobs in the same workflow (so no other job could have
tried accessing that folder).
Besides, NFS (or any shared system) provides file synchronization natively. But
that's not the problem anyway because no other machine will try to access that
folder until the present one has finished the job.
