snapraid-runner cronjob using a lot of RAM when not running?

[Arakon]

Hi.

I'm running Snapraid with MergerFS on 2 12TB merged HDDs with another 12TB drive for parity on Debian 12.

snapraid-runner is taking care of triggering the actual synching.

I currently have the following "sudo crontab -e" entry:

00 04 */2 * * sudo python3 /usr/bin/snapraid-runner/snapraid-runner.py -c /etc/snapraid-runner.conf
This works fine, as intended, every 2 days.

However, I noticed that I now have the "cron" service running continuously with 1.35-1.75GB of memory usage for a day or so after executing, then eventually stops until the next time the cronjob for snapraid-runner is called.

No other cron jobs are currently running (there's one entry for a plex database cleanup, but that only runs once a month and has been on the server for over a year without ever showing this behavior, until snapraid-runner was added).

This also means that cron is using more RAM than any other application or container, including Plex Server, Home Assistant, etc.

top reports:

as the main memory users.

Any idea what could be going on here? It seems to me like snapraid-runner is not quitting properly after the run or something.
