Backburner makes me angry (again) because of awkward Job Submission

Hey,

I have written a script to render a number of images, lets say 32. This is done inside a nested for loop (lets say 4 loops nested into each other). Inside the inner loop lies my max quick render command. Everything is working fine, it renders out nicely!

I thought it might be a nice feature to have the option of creating a renderjob for Backburner for each image. Now I have simply replaced the render command with some lines like so:

--gMan holds the connected Manager, counter holds the current loop No.
local theJob = gMan.newjob() --create job	
 
if gIncludeMaps do theJob.includeMaps = true	
theJob.name = gJobName + "_" + counter as String + (create_suffix()) as String
 
theJob.submit() --submit using all servers		

It works, BUT: only every second job is submitted. There are no errors (like "Error: Duplicate File name"). I dont get it. It works fine with images and I can print out the job names, they are unique and correct for each job. But it does not get submitted. If I have 32 jobs to submit, I end up with 16 in the Backburner.
Does someone have any idea why? Does Backburner have problems accepting a number of jobs in a short time or whatever?

Cheers
