Process stalled when running make_prg on a set of fasta file

[mthang]

I am using make_prg tool (i.e make_prg from_msa ...) in a pipeline that I am refactoring. The make_prg tool happpens to stall when I run my pipeline. What I have noticed is the usage memory keeps growing until the memory on my system exceeded the limit. Then, the make_prg process was stuck. I have spent some time to look into the script below and modified the script by replacing the multiprocess with queue. It seems to work, but I am not certain if that would affect the logic of the tool.

make_prg/make_prg/subcommands/from_msa.py

Line 182 in 1f347a2

with multiprocessing.Pool(options.threads, maxtasksperchild=1) as pool:

Thanks
