This alert is sent if connection to a recorder service is reestablished.
No further action required.
However, if you receive this pair of alerts on a regular basis, your network is probably overloaded.
If that is not the case, please contact the support service and send the log files of the related service - agentcontroller.log, captureagent.log.
Log files are available under "APPLICATION_FOLDER\log" (by default C:\Program Files\Verba\log) folder on each server.
