A quick question, sorry if it is already explained else where.

Using bacula 2.2.0 in my DIR and SD on a 32 bit CentOS 5 server. Trying 
to backup a 32 bit XP machine running 2.2.0 bacula client.

When I set up the parameter "Maximum Concurrent Jobs" to "1" in FD 
configuration file, all (initial) backup eventually appears to be 
canceled after writing all the right number of files and right number of 
bytes to SD. Ran at least half a dozen of such jobs, all ended up being 
canceled. This is the message from one such job.

Then I bumped the value of "Maximum Concurrent Jobs" to "2" in FD 
configuration file, and the job ran as expected. Please see output below.

Any suggestion, why a single job is viewed as 2 Concurrent Jobs (at 
least from FD's perspective)? All other configuration in DIR and SD were 
kept same during these events.
