Job fails due to being out of memory

[Eve Alessandra Sangalang]

Good day. 

I am currently running a job for the core gene alignment of approximately 3900 E. coli genomes (4.5-5.0MB each). I am allotting 32 cores and 200GB of memory; however, my job keeps failing for modeltest-ng. 

I inspected the log files and it states that that the Max thread num is 10 MB. I am confused as to why this is the case, and I cannot find a way to customize it (if customizable). 

I am asking for assistance on an estimate of the amount of cores and memory I should be allotting, or if you have other advice for me. Thank you very much.
