par pool error 2017b

I running a parfor loop parpool work with 12 workers (I have tried 16 too) in matlab 17b. The job starts normally and works through half of the loop until it suddenly stops with the following error:

Error using parpool (line 113) Failed to start a parallel pool. (For information in addition to the causing error, validate the profile 'local' in the Cluster Profile Manager.)

I have seen in previous support questions that this might be related to the timezone, and so I added a line in my main matlab code of: setenv('TZ','Asia/Jerusalem') just in case. This did not solve my problem (although it did solve a warning of timezone I used to get in the beginning of my run). Would appreciate some help, Thanks, Hadar.

I suggest contacting MathWorks support to help resolving this problem.
