EZZ0797I

Explanation
 Specifying the EXPLICITBINDPORTRANGE parameter
on the GLOBALCONFIG statement  might not have the expected outcome
when the TCP/IP stack is configured to be in  a common INET (CINET)
environment. Application requests to bind to  INADDR_ANY and the unspecified
IPv6 address (in6addr_any) and port 0 might not result in successful
connection setup, unless one of the following criteria are met:  CINET has been configured but only a single TCP/IP stack is active
at any time. 
Multiple TCP/IP stacks are active but all applications that perform
bind  requests to INADDR_ANY and in6addr_any and port 0 have affinity
to a specific TCP/IP  stack.

System action
 TCP/IP profile processing continues. Application
requests to bind to  INADDR_ANY and in6addr_any and port 0 might not
result in successful connection setup, unless  the specified criteria
are met.

Operator response
 Contact the system programmer.

System programmer response
 To ensure that the connection setup
is always successful when you are using distributed DVIPAs that are
specified on SRCIP rules destination configure an explicit bind port
range. You must also configure your system so that the stack is not
part of a CINET environment or ensure that the specified criteria
are met.
