I have noticed I have missed blocks for some of the delegates.
There were no network interruptions. I had no ping loses to at least 30 different ip addresses (this is a service running constantly) and this list includes seed nodes and other delegates.
Delegate was connected to the seed node at all times.
Delegate's connections were above 20 at all times.
There were no HDD or CPU spikes that would prevent.
What might have caused missed blocks?
Anyone else experiencing the same?
Furthermore I've noticed some delegates consistently producing blocks with negative latency. Are they manipulating the client in some way? What could've caused this ?
UPDATE: My clock is synchronized but the cliend shows NULL on the time diff. Is this expected?
