Created attachment 558334 [details] 1315255599464.log User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:7.0) Gecko/20100101 Firefox/7.0 Build ID: 20110824172139 Steps to reproduce: Running firefox 7 with Google Main+Google Calendar app tabs open, browsing as normal with two other tabs. Actual results: Sync fails without warning, unknown error. Attached the log file - appears to be no lock on the sync service. Expected results: Well, sync should have worked... :-)
The message about the lock just means that a second sync tried to begin whilst the first was in progress. Nothing to worry about. This looks like a server error of some kind. Most likely it's a temporary condition; "503" indicates that the service is unavailable. Are you still seeing problems now?
There was a server issue earlier today. Are you still able to reproduce the issue with Sync Now? It should have been resolved since then.
Appears to be all fine now. No error logs are being created and pages visited are syncing between devices. Thank you!
