1770379 - Login delay from external web application server after CMS restart


After restarting the Central Management Server (CMS) there is a login delay up to several minutes until the login finally proceeds. This is happening from an external web application server (WAS).

When analyzing the TCP/IP states, the following scenarios can be observed:

Before shutting down:

tcp        0      0         ESTABLISHED 
tcp        0      0         ESTABLISHED 
tcp        0      0         ESTABLISHED 
tcp        0      0         ESTABLISHED 

( being the WAS, being the CMS host, 50000 being the CMS Request Port - dynamically assigned)

After shutting down the CMS, all connections are releasd. When restarting the CMS, this scenario is revealed:

tcp        0      1         SYN_SENT    

The SYN_SENT state of the connection means that the WAS attempts to connect to the CMS on the old request port. That is the normal behaviour. Normally the destination returns a TCP RESET in case the port is closed. This is not the case in this scenario. The connection stays in SYN_SENT until it times out.
