SWAN Member Library Staff: After extensive troubleshooting alongside SirsiDynix support and adjustments to our MobileCirc authentication procedure, we're happy to announce that the app is again stable and ready for library logins, although we're still working to fully resolve the issue. Through our troubleshooting, we determined that MobileCirc performs a query during the login/authentication process to collect delinquent patrons barcodes in the event that the app needs to run offline during that day. This is similar to how WorkFlows collects a user delinquency file for use in offline mode. At our current volume of users matching this criteria, the query would cause MobileCirc to become unstable, leading either to higher CPU loads on the Symphony server or a timeout during authentication. SirsiDynix has proposed the development of a new MobileCirc version that permits offline delinquency as optional. Since SWAN does not currently support MobileCirc in offline mode due to several other previously identified bugs impacting holds and item statuses, this is the ideal solution to the issue. However, development of this version could take up to several months, so through some trial and error, we've managed to throttle the volume of delinquent users passed to the offline file for both MobileCirc and WorkFlows. Currently, patrons with a last activity date greater than two years are not reflected in the offline delinquency. This will only be temporary until the new version of MobileCirc becomes available. We thank you for your patience throughout the troubleshooting process. -- SWAN Library Services 800 Quail Ridge Drive - Westmont, IL 60559 Email: help@swanlibraries.net<mailto:help@swanlibraries.net> Phone: 844-SWANLIB (844-792-6542) https://support.swanlibraries.net/
