This could be an issue with monitoring persistent TCP connections. If you utilize these in your environment then some of the packets will not have the connection details as DCRUM would expect. You can make changes to your configuration to resolve this issue. Here is a link to a troubleshooting page where this scenario is mentioned:
Check your data quality on the AMD, from the screen shot, it appears you're missing packets rather frequently, there's counts against all the metrics that imply packet loss.
- sessions not seen from the beginning
- incomplete SSL handshake
- packet loss during handshake
- reused sessions with no primary session seen before
- corrupted handshake
Get the traffic quality 100% and your SSL problems will largely resolve themselves.
