MDCS-question "UNEXPECTED ERROR in dctEvaluateTask." in all tasks

We have a LSF cluster where we can send jobs. I send one matlab file that includes:

sched = findResource('scheduler','type','lsf');
set(sched,'ClusterMatlabRoot','/applications/matlab/2009b_dcs');
set(sched,'DataLocation','/home/myResultLocation);
set(sched,'SubmitArguments','-q mdcsQueue');
j = createJob(sched);
createTask(j,@testStartScript_1,0,{});
createTask(j,@testStartScript_2,0,{});
createTask(j,@testStartScript_3,0,{});
submit(j);
waitForState(j,'finished');
destroy(j)

The start scripts set a few parameters and then calls a main function. The results are saved on a disc. It all works and the results are correct and the one job, with different tasks, is deleted when finished. The only thing I would like to add is to print out if there are errors/warnings in a certain task in the file that sends all the tasks. I have found a way to print out the errors but I get "UNEXPECTED ERROR in dctEvaluateTask." in all tasks regardsless if it runs as it should or if I introduce an error that crashes the code. The crash and the reason for that I do not get.

Is there a communication problem with the file creating the tasks and the tasks themself?

We also have licenses for 2011b_dcs and when I run with that version I also get all the results correctly stored (if they run as they should) and with the same type of error in all tasks, and no other errors (even if I introduce some).

If I however start the file that creates the one job and the tasks with 2011b_dcs and in the file the code says 2009b_dcs (as shown) I can manage to get another error message in all the tasks, which is nice.
