Lot of Connections, no Clients / Pool
Hi, 

at one of my two servers i suddenly got the following issue:

I get a lot of Connections like that

    Connecting: 194.94.108.xxx 
    Authenticated 194.94.108.x

But still  
 
    [10/17/2018 9:49:03 AM] heartbeat; connections client/pool: 0/0; jobqueue: 0.0k; speed: 0.0kH/s

Also i get the following:

    FLECK: Application Error A call to SSPI failed, see inner exception.

All happened while running good for 5 Days - Server restart didn´t fixed it
 
Thanks!
