Terminal disappears automatically when runs classification command

[pratibha-kadam]

I have used Kraken2 before on the same 64 GB RAM computer with 16 threads. The drive where the data and output directory are present has more than 300GB of space. I was trying to Kraken2 classification step for paired end data. In my database, I have only 3 k2d database files. When I run the command every time it takes 4-5 hours to load the database information and when it processes the file it suddenly disappears after a while.

I tried it a couple of times but it vanishes every time.

Please let me know where I go wrong or any system issue.
