NSSREAD ERROR CONDITION (1337)
TITLE: NSSREAD READ ERROR CONDITION STATUS #### (1337)
AUTHOR: JOE PARATORE
DATE: 12/30/93
DESCRIPTION
-----------
-- nssread read error condition status 8420 (1337)
-- nssread read error condition status 8444 (1337)
A status 8420 error suggests you had communication error
between nodes, which could lead to the 8444 status. If the
network was busy, the number of retries may have exceeded
its setting. Assuming both nodes stayed up.
Extract from VAX SYSTEM SERVICES
--------------------------------
LINKABORT, network partner aborted logical link.
Facility: SYSTEM, System Services
Explanation: The remote process disconnected the logical
link either because the process exited
prematurely, or because it is the normal way
for the process to disconnect the link.
User Action: Check to see if the node is reachable and
retry.
PATHLOST, path to network partner node lost
Facility: SYSTEM, System Services
Explanation: The path to the remote node is lost due to
too much network activity or communications
problems.
User Action: Wait, then check to see if the node is still
reachable.
CORRECTIVE ACTION
-----------------
To check on retries do:
$ MCR NCP SHOW othernode COUNT
and
$ MCR NCP TELL othernode SHOW thisnode COUNT
The following formula will assist in determining if it is
necessary to raise the Retransmission Factor.
The Retransmission Factor is the number of retries permitted
before a link is aborted. If the formula below yields a
number higher than 10%. Consider raising the Executor
Characteristic Retransmission Factor.
FORMULA
-------
100*responsetimeouts/messagessent = % of retransmission
To reset the Retransmission Factor,
$ MCR NCP SET EXEC RETRANS newvalue
ADDITIONAL INFORMATION
----------------------
You should also look at LINE and CIRCUIT counters. There is
also the possibility that the applications sharing the
link(s) were stalled for too long of a time. If problem
persists contact your Digital Equipment Specialist.
Tip:
---
You can easily determine the message associated with the
return status by using the following command, or taking
advantage of the VAX SYSTEM SERVICE SYS$GETMSG.
$ write sys$output f$mess("8444")
%SYSTEM-F-PATHLOST, path to network partner node lost
