What was the UX? Have you been seeing Sync error bars?

Comment 2

[Philipp von Weitershausen [:philikon]]

Seeing NS_ERROR_NET_RESET in logs is perfectly normal if the servers are having problems keeping up with the request load. "Could not acquire lock" makes sense too. You're trying to kick off a sync while another one is still running, presumably because the requests are taking a long time to be processed by the server (because it's under heavy load.)

These are errors that Sync deals with internally. Just because they pop up in the log doesn't mean something's actually wrong. So long as they're not shown to the user, everything is fine.

Please reopen if you saw an error bar.

correct, no error bar for this scenario.
