f “Connection to remote node failed; resuming”
This error is reported when an RST has been received. If the error persists,
verify that applications are using proper IP addresses and that the remote
host is not experiencing resource limitations. Entry 3 is the endpoint (TCP
connection identifier). Entry 4 is the TCP state:
1 = CLOSED
2 = LISTEN
3 = SYN-SENT
4 = SYN-RECEIVED
5 = ESTABLISHED
6 = FIN-WAIT-1
7 = FIN-WAIT-2
8 = CLOSE-WAIT
9 = LAST-ACK
10 = CLOSING
11 = TIME-WAIT
Entry 5 contains TCP flags.
10 “Connection to remote node failed; resuming”
This error is reported when a TCP connection has been aborted. The TCP
layer has retransmitted a segment the maximum number of times and the
remote host has failed to ACK the segment. Check network connectivity and
the remote host’s operational status. Entry 3 is the endpoint (TCP connection
identifier). Entry 4 is the number of retransmissions.
11 “Connection to remote node failed; resuming”
This error is reported when a connection has been aborted after the remote
host failed to respond to “keep-alive” probes. Check network connectivity
and the remote host’s operational status. Entry 3 is the endpoint (TCP
connection identifier). Entry 4 is the TCP state as shown above. Entry 5 is
always zero.
12 “Connection to remote node failed; resuming”
This error is reported when an SYN has arrived in an improper state. If the
error persists, verify that applications are using proper IP addresses and that
the remote host is not experiencing resource limitations.
13 “LAN system - software fault; resuming”
14 “LAN PROM/software mistmatch; running soft Sw util”
Trouble encountered initializing TCB. Entry 3 is the endpoint (TCP
connection identifier).
15 “LAN PROM/software mistmatch; running soft Sw util”
Trouble encountered sending SYN. Entry 3 is the endpoint (TCP connection
identifier). Entry 4 is a developer-significant error code.
16 “LAN PROM/software mistmatch; running soft Sw util”
Deallocating TCB before close. Entry 3 is the endpoint (TCP connection
identifier). Entry 4 is the TCP state as shown above.
17 “Connection to remote node failed; resuming”
Sent RST in state processing due to clash in packet fields and their expected
values in this state. Entry 3 is the local endpoint, Entry 4 is the state, and
Entry 5 is the value of the code field of the offending packet.
