Fatal inter-address communications error VMCF RC=number User=lastuser
Explanation
 The Virtual Machine Communication Facility "VMCF" encountered
a network pacing response code. The VMCF return codes below describe
the different types of error conditions that may cause the fatal inter-address
communication error.  Return Code
Cause
1
Invalid virtual buffer address
2
Invalid subfunction code
3
Protocol violation
4
Source machine not authorized
5
TCPjobname user not available
6
Protection violation
7
Sendx data too large
9
Target machine in quiesce state
10
Message limit exceeded
11
REPLY canceled
12
Message not found
13
Synchronization error
15
Paging I/O error
16
Incorrect length
17
Destructive overlap
18
User not authorized for PRIORITY message.
19

System action
 TCPIP halts.

Operator response
 Tell the system programmer the VMCF communication
error encountered.

System programmer response
 Use the return code displayed in
the list of error responses to determine the cause of the error.
 If
the return code=5, verify that the TCPIPJOBNAME is correctly specified
in the TCPIP.DATA data set.  Ensure that you are using the correct
 TCPIP.DATA data set.
 For other return codes, correct the error
using the different resources stated below that may apply to the error
condition specified.  Once the error is corrected restart TCP/IP.
 For more information on the VMCF facility and return codes see the z/OS Communications Server: IP Sockets Application
Programming Interface Guide and Reference.  For information on configuring the TCPIP.DATA
for the VMCF, see the z/OS Communications Server: IP Configuration
Reference.  If the error is beyond the scope of these
resources, contact the IBM® Software
Support Center.
