Send and Receive Failures
Most Send and Receive failures are timing-related. They usually do not
abort the tests. Listed below are the Send and Receive failures which do
not abort the tests:
Send and
Receive
Errors
TCP MESSAGE RECEIVE FAILED Packet # {Remote}
IPCSEND FAILED Packet # {Remote}
DATA RECEIVE FAILED Packet # {Remote, Local}
1ST MASTER SEND FAILED {Local}
SEND FAILED Packet # {Local}
Summary Messages:
TCP TEST FAILED
LOCAL: SEND TO REMOTE FAILED
LOCAL: RECEIVE FROM REMOTE FAILED
LOCAL: SEND AND RECEIVE FAILED
REMOTE: RECEIVE FROM LOCAL FAILED
REMOTE: END TO LOCAL FAILED
REMOTE: RECEIVE AND SEND FAILED
Note the location in the program where the error occurred. For each
error, examine the SOCKERR numbers and the Protocol Module
numbers returned. Save the error information. Follow the “Actions” for
the Protocol Module or NetIPC SOCKERRs, both listed in the
NS 3000/iX Error Messages Reference Manual.
Socket Creation Failures
Socket creation failures and Network IPC Connection errors cause a
test to terminate. Listed below are Socket Errors which abort the tests:
Socket Errors
UNABLE TO CREATE SOCKET {Local & Remote}
CONNECTION REQUEST FAILED {Remote}
RESPONSE TO CONNECTION FAILED {Remote}
LOCAL IPCRECVCN FAILED {Local}
Following these errors on the console screen are a SOCKERR and a
Protocol Module error. Copy the error messages on the user and system
console terminals. Follow the “Action” for the SOCKERR and PM
errors, respectively listed in “Network Interprocess Communication
Errors” and “Network Transport Protocol Errors” in the NS 3000/iX
Error Messages Reference Manual.
Checksum Errors
The XPVAL software line tests enable checksum in the TCP protocol of
the network transport subsystem. “Checksum” errors may be returned
to either console. If “Checksum” errors appear along with “Send and
Receive failures” listed above, then your system may have hardware
link problems; see “Investigating the Link” in the NS 3000/iX Error
Messages Reference Manual.
