Cron error - No MTA installed

HI team
my deepstack instance will do a single inference slowly, then not respond to futher requests. The logs show an error due to cron?

Also if you can shed some light on what task cron is executing that would be interesting, sounds like it could be a db backup? Maybe running docker with sudo is a solution

OK deepstack is not processing a single image now, and no errors in the logs, I guess I need to rebuild the container?

Hello, you only need to restart the container. I am curious, how long has deepstack been running before this behaviour occurs?

I John, I was having the issue even after restarting the container. I restarted my machine and everything is working fine for the timebeing. I think the container was running for over 12 hours by the time I noticed the reported error, I am calling the API roughly every 10 seconds
