 * Hello Tom,
    Thanks for trying out Prime Mover. This error could be caused by 
   different factors that could be hosting-related, connection interruption or a
   multisite under maintenance mode (e.g. updating plugins). Fatal error can also
   cause this error.
 *  To help us understand the true origin of this error, can you please provide 
   more details on your issue by following this [troubleshooting guidelines](https://wordpress.org/support/topic/please-read-before-you-post-5/).
   Please describe the steps that results to this error. Once you followed the guidelines
   with `WP_DEBUG` enabled, we will know this error better and we can possibly fix
   it.
 *  Also does this happen during export? or import?
 *  If these happens during export, can you try exporting database only and see 
   what happens? If exporting database works but does not work with export media
   files or with plugins, your site might be too heavy for your current hosting 
   setup.
 *  In this case, you can try to break down the export into different stages, you
   can [read more tips here](https://codexonics.com/prime_mover/prime-mover/tips-and-techniques-in-migrating-large-sites-with-prime-mover-plugin/).

 * I’m closing here as this ticket is now outdated. We have released version 1.0.9
   with some fixes on affected servers particularly AWS (Amazon web services) Lightsail
   on Bitnami. Feel free to re-test and open new ticket with the requested details
   if necessary. Thanks!
