sounds fairly extreme to perform a loginit
what sort of solution are you using, VoIP? Trunkside? Extensionside? Observation? Can you see the green activity icon in the monitor application when in channels mode? Are your channels showing any errors?
I had a similar issue with VoIP recording when the SPAN port hadn't been configured correctly, if you are using VoIP check no one has made any changes to your SPAN/Mirror configuration. Also do you have multiple SPAN connections in the logger and one of them is failing?
