I am currently running mothur in batch mode (Linux version, mothur v.1.48.0), however I seem to be running into trouble at the very first step. Although the make.contigs step begins sucessfully, it seems to crash abruptly mid-run returning a termination message with an exit status 137 (I am running mothur in HPC). I believe that this refers to a memory problem. To resolve this, I tried to increase my total memory to 70 gb, 75 gb, 80 gb and even 150 gb while reducing the number of processors. I still end up with an exit status 137 no matter how high I increase the total memory.
This is the output from my error file.

I have a total dataset size of ~48gb in the gz format. I would be sincerely grateful if you could help me resolve this issue!
Many many thanks!
