What version of AtoM are you using? Was this a fresh install, or an upgrade from an older version? Have you followed our recommended installation instructions? If yes, are you using Ubuntu 16.04 or 18.04? If no, what changes have you made?
Are there any relevant messages that show up in the Nginx error logs? You can also check the atom-worker logs with the following:
- sudo journalctl -f -u atom-worker
In the 2.5 release, we changed the default job scheduler atom-worker configuration block. This should make it more persistent, but also changes the behavior. So, a couple things to note about this. First, if you've upgraded from an older version, make sure that your atom-worker config file looks like this now:
Second, note that while the job scheduler shouldn't die as much, if you restart it more than 3 times in 24 hours, then you will need to manually reset the restart limit. You can do this like so:
- sudo systemctl reset-failed atom-worker
- sudo systemctl start atom-worker
Does the import work if you try running it from the command-line instead?
Any further information you can provide will help us provide better suggestions on next steps.
