All agents loose their CDT connection at the same time.  In the corresponding logs you see error messages such as:
 
 ERR> Lost connections to all CDs/ETCs
 
In the CD logs you may also see message such as:
 
[Cem:XX_Core]: Connection [Connection/03311C50 [Cem:XX_Core]] very close to timing out - [2] seconds to timeout of [10] seconds
 
This is typically due to a VM issue with the Host machine.  Typically a timing issue or something related.
