Network Transport Protocol (PMERR) Error Messages
-20 MESSAGE: CONNECTION ENTRY ALLOCATION FAILED
CAUSE: TCP was unable to allocate a connection entry. Potential
reasons include running out of memory space for resident data
structures, table management failure, or TCP internal error.
ACTION: Enable class 2 logging for NS Transport if not previously
enabled. Locate matching log instance for resource error if possible.
Error message will indicate class 2, subsystem 3, entity TCP, location
102xx. Parameter is table management error returned. (Sign bit set
indicates error, not set indicates warning.) Consult MPE/iX operating
system error documentation if available, submit an CR with this
information if necessary.
-21 MESSAGE: CONNECTION ALREADY EXISTS
CAUSE: An attempt was made to open a connection which already
exists.
ACTION: The connection attempt used a set of local and remote socket
numbers (sap) and local and remote IP addresses which were identical
to the set in use by a currently functioning connection. If you are
connecting from a user socket, open a new local socket or allow
transport to choose a random sap in the connect call. If you are
connecting using transport chosen random saps, the original connector
must have marked the local socket for immediate reuse. In this case,
retrying the connect should succeed.
-30 MESSAGE: SOCKET ALLOCATION FAILED
CAUSE: TCP was unable to allocate a socket entry. Potential reasons
include running out of memory space for resident data structures, table
management failure, or TCP internal error.
ACTION: Enable class 2 logging for NS Transport if not previously
enabled. Locate matching log instance for resource error if possible.
Error message will indicate class 2, subsystem 3, entity TCP, location
102xx. Parameter is table management error returned. (Sign bit set
indicates error, not set indicates warning.) Consult MPE/iX operating
system error documentation if available, submit an CR with this
information if necessary.
-31 MESSAGE: SOCKET ALREADY EXISTS
CAUSE: An attempt was made to open a socket with a TCP sap number
which is already in use by a currently open socket.
ACTION: Close the original socket.
-40 MESSAGE: INCONSISTENT IPC STATE
CAUSE: A TCP operation was attempted which conflicts with expected
(IPC/BSD sockets) operation in this state.
