When a recording trouble occurs when playing back recorded vide data (e.g., data is notfound), you can guess the cause by checking the Event Logs of the VK-64/VK-16 andStorage Server Log (re_log) .2379 TroubleshootingTroubleshooting for RecordingEventConnection toaddress> error: Erroroccurred (:)Ex.

Review the recordingschedule or add servers as required.· Use the Task Manager to find outthe application causing the problem.· If the VK-64/VK-16 module(AE.EXE) is causing the problem,the event generation frequencymay be too high. Try the following:- Shorten the Maximum retainedhistory setting for the recorded data- Reduce the number of events togenerate- Add servers to distribute the load.· Check the drive for recordingvideo data.· If you are using NTP to adjust time,shorten the synchronization intervalwith NTP (e.g., 7 days ➝ 1 day).Shorten the Maximum retainedhistory or add HDD. Also, reviewthe recording schedule.Log |
