out-of-memory

[JhinAir]

Hi, @agudys

When I run kmer-db, I always came across the issue of 'out-of-memory', even testing with very small input fasta or the example fa in your 'data' directory. My command is: kmer-db build -k 31 -t 2 test.list test.db

The file test.list only includes one sample: data/MN908947, but this command would consume more than 100Gb of memory, and get killed: /var/spool/slurm/d/job1132243/slurm_script: line 10: 1165089 Killed kmer-db build -k 31 -t 2 test.list test.db slurmstepd: error: Detected 9 oom-kill event(s) in StepId=1132243.batch cgroup. Some of your processes may have been killed by the cgroup out-of-memory handler.

The same error occurred when I chose Kmer file produced by KMC as input. How could this be? Could you please help me with this?
Thank you! Best~

This problem occurred when kmer size is set to 31, which is larger than the maxium in the latest version. Why is that?
