At some point I'd like to optimize plex-sync so that it's not holding so much information in memory, but as a temporary workaround, you can increase the node heap size. Node limits itself to around 1.7GB of memory on 64-bit machines, so for instance to run with 4GB of memory:

$ node --max-old-space-size=4096 `which plex-sync` [...]

Sorry to bump an old thread, I am still getting memory errors with even as much as 32gb. Does anyone know if there is a improved fork of this or a better solution that exists now? Need to sync watched states in two libraries and don't have file access to one server nor do I want to risk messing directly with .db files. Any help is greatly appreciated.
