Authentication Service ,  

26 December,14 at 09:45 PM

Problem:
A large number of connections, mostly for port 88 in the CLOSE_WAIT state are being seen on the DC tied to the lsass.exe process. Connections on the Linux side timeout in FIN-WAIT-1 state. 

Information:
 It is the DC side that is waiting for its application to close socket to transition to LAST_ACK. but the close() call never came. 
Research into the into the CLOSE_WAIT status on the DC we found lots of CLOSE_WAIT complaints on internet for MS. 
Please see the following non Centrify link for information on this issue specifically for Kerberos:
