How to solve a parallel pool start failure?

I am currently running MatLab R2014b on Ubuntu 14.04. I am trying to call MatLab code from a Python script and whenever I do so, I get one of the following error messages
Error using matlabpool (line 148)
Failed to start a parallel pool. (For information in addition to the causing error, validate the profile 'local' in the Cluster Profile Manager.)
Error in plmDCA_symmetric (line 84)
matlabpool('open',nr_of_cores)
Caused by:

Error using parallel.Job/createTask (line 273)
The expected job file /home/felix/.matlab/local_cluster_jobs/R2014b/Job3.common.mat does not exist.
However, when validating my 'local' profile all tests pass and no problems occur. Even when running the program from within MatLab, it works!
Is there a way to resolve this issue?

That error is related to the communication channels that the parallel pool infrastructure is trying to set up. I'm not quite sure what you mean by "an external pipeline" - is it possible that in that situation, there are different firewall settings?

Are you running multiple copies of this simultaneously? What OS are you using?
