MATLAB crashes when running in a parallel bash mode

Hello,

bear with me for a few paragraphs while I explain the background of the problem as this is a meta-programming issue.

I have a bash script that I use to run MATLAB that looks like this:

xargs -P25 -d'\n' -I{} -t matlab -nodisplay -nodesktop -r "try;runinput={};MD_script_DoE_mass_time_RLV_Ncvx_SOCP1_14;end;exit" < MD_list_DoE_mass_time_RLV_Ncvx_SOCP1_14.txt

MD_script_DoE_mass_time_RLV_Ncvx_SOCP1_14 is a script file that contains a process, which uses the input case from MD_list_DoE_mass_time_RLV_Ncvx_SOCP1_14.txt. The bash script is reading line by line this text file, which really just contains numbers in descending order from 1 to 25. The script file then reads this as a variable called runinput and starts the process (I have a table in the matlab script file that gives the inputs to all the other variables of the problem based on a value from 1 to 25).

When I run the bash script, out of all the 25 processes, only 4 make it through. I get a whole bunch of errors for the others that indicate the following:

I also get an error on the ssh machine which I have attached since its too long to show here.

What is causing this issue? I have done some sample runs on my laptop with a few different runInput cases and it runs fine. It's a little bit tedious to debug the issue seeing as there are a lot of files involved and I don't run these processes with a GUI.
