I can believe that the changes you made resolved the problem, because a number of the problems seem to be a result of several things happening at the same time. However, the root of the problem is a "race condition" (a bug) in the Bacula SD. Hopefully, the next version of Bacula will fix this. If I get a good dump showing a race condition, we can probably send a patch, but without knowing exactly what is going on (i.e. a good dump) there isn't much we can do.
