It’s a 1GB Linode configured to have a 512 Swap drive.
It was trying to sync about 2.3 GB of data split between 47K files. I also configured Ignored list to filter files that could be easily regenerated. At one point during this operation, my source “master” machine having sync marked as “Send Only” actually showed it is out of sync, requesting to “Override Changes”. So I haven’t clicked that button, it sounded intimidating, so while that was in effect, syncing was under way and then approximately about 99% done that crashing appeared. So I am not sure if these two things are connected or not.
In fact, I edited ignored list while original syncing was still under way, if that helps
