Your software
My Mautic version is: 3.3.1
My PHP version is: 7.3.26
My Database type and version is: MySQL 5.7 AWS RDS

Your problem
My problem is: After upgrading to version 3.3.1 we often have background segment imports stall out. We can toggle them off an on to get them to continue. This is happening with imports of 20k records where in the past we would import lists with 100k records without them hanging.

These errors are showing in the log:
I have not found any errors in the error log that appear to relate to this.

Steps I have tried to fix the problem:

I’m not sure what to try. We are not running out of memory or no other error appears to be getting logged.

Hey, are your cronjobs working properly?
Crons should use folder /bin/ not /app/ !

We did update all of our crons to use /bin/ instead of /app/. We can try to execute the mautic:import task manually to see if it provides an error or more information.
