StatsDatabaseApplication Time Jumped Back message

(Wowza Streaming Engine 4.1.2 build13947)

Our server is seeing several cases per day of this server WARN message. "
StatsDatabaseApplication:write(Level: MINUTES) Time jumped back."

When this occurs, the Network Bits Out and number of Connections increases 8-10x the normal number. It occurred 3 times during a live stream, but also occur when not publishing a live stream. During the live stream, the access log time stamp indeed 'jumps' backwards in time approximately 30-40 seconds.

Example:

10:19:40 jumps to 10:18:27 thru 10:19:40

When the log catches back up to 10:19:40, PLAY is seen for all connections.

11:18:27 jumps to 11:17:04

13:16:58 jumps to 13:15:40

Same thing except no live streams during that time.

15:15:40 jumps to 15:14:14

When it occurs, the live stream visible freezes until the user manually disconnects & reconnects, or the time stamp corrects itself after 30-40seconds.

These errors usually indicate that there is an issue with the Monitoring module and the system date for logging the stats files. You can try resetting your stats db files to see if it resolves your issue. Do note that these steps would result in your previous (historical) stats being unavailable going forward. I would recommend that you have rollback procedures in place.
