Action:

Report this problem to your HP support representative.

Message 113 - Unknown destination node <number>

Explanation:

This message is issued when znode fails to get a node entry from a node number in the symbol table.

Action:

This is a znode internal error. Report this problem to your HP support representative.

Message 115 - Error on write: <reason>

Explanation:

This message is issued when znode detects an error on writing to the LDM.

Action:

Report this problem to your HP support representative.

Message 116 - Bad magic number <number> from write

Explanation:

Action:

Report this problem to your HP support representative.

Message 117 - Message len (<number>) doesn't match result from write(<reason>)

Explanation:

This message is issued when znode detects that there is a mismatch in message length between the length of the message buffer and the length resulted from the write operation performed on the LDM.

Action:

Report this problem to your HP support representative.

Message 119 - Error accessing /dev/zremote: <reason>

Explanation:

This message is issued when znode fails to access /dev/zremote.

Action:

Report this problem to your HP support representative.

Message 120 - Duplicate linkname <name> ignored, same as <name>.

Explanation:

This message is issued when znode detects two links with identical addresses; and hence one of the links is ignored.

Action:

None.

Message 121 - Warning: Could not set RT priority (errno=<number>:<reason>)

Explanation:

This message is issued when znode fails to set real time priority.

Action:

None.

Message 122 - Warning: Could not set memory lock (errno=<number>:<reason>)

Explanation:

This message is issued when an attempt to lock znode in memory failed.

Action:

None.

Message 123 - Can't create /dev/zremote, error: <reason>

Explanation:

This message is issued when znode fails to create the/dev/zremote device file.

Action:

Correct the problem with the given reason if possible. This device file can be created manually using mknod (refer to the ACC Installation and Configuration Guide, Appendix A on "Device Files") with read and write access. If this also fails, contact your HP support representative.

Message 124 - Can't get the znode semaphore: <reason>

Explanation:

This message is issued when znode fails to obtain the znode semaphore.

Action:

Report this problem to your HP support representative.

Message 125 - znode daemon is already active, terminating this copy

Explanation:

This message is issued when znode detects that the znode daemon is already active in the system; hence this copy will be terminated.

Action:

None.

Message 126 - Message from node %d discarded/ Too long (%d bytes)

Explanation:

A message from the specified remote node was too long. The message was discarded. The maximum sized message supported is 65,534 bytes. The local node received a remote message/request which exceeded this length.

Action:

Check the application implementation and verify that the maximum message length for remote request is not exceeded. If the application is correctly coded, this may be an internal defect and you should contact your local HP representative.

Message 127 - Error on socket recvfrom() call (errno=%d:%s)

Explanation:

System call recvfrom() failed with the given error.

Action:

Examine the system error returned (errno) and take corrective action.

Message 128 - Possible socket read truncation. Received %d bytes. Expected %d bytes.

Explanation:

A message received from a remote node was shorter than expected. Data may have been lost. This is an internal error.

Action:

Contact your local HP representative.

Message 129 - Unknown source node %d.

Explanation:

The local node received a message from a node that is not configured in the local .answ file.

Action:

Review the node configuration on all nodes to ensure it is consistent.

Message 130 - Unknown link for source node %d.

Explanation:

The IP address from which the remote request arrived does not match any of the IP addresses defined for the links on that node in the local TTGEN .answ file.

Action:

Review the node configuration on all nodes to ensure it is consistent.

Message 131 - Remote node %d marked down. Packet on queue %d seconds

Explanation:

The local node received a partial message from the remote node, but the full message was not received within the allowed amount of time. The status of the remote node has been set to "down". This could be due to the remote node, itself, physically failing or to a failure in the communications link.

Action:

Determine why the remote node is down and take corrective action. Note that communication will automatically resume once the link between the two systems has been reestablished.

Message 132 - Bad packet revision %d received from node %d. Packet dropped.

Explanation:

The znode program on the remote node is not of a compatible revision with the znode program on the local node. All ZCOM nodes which communicate using the ZNODE functionality must have identical revision of the ACC software installed.

Action:

Update the remote node with the same version of the ACC products as the local node. (Note that the znode program is supplied with the ACC Base Software product as well as the X.25/ACC Bundled ACC product.)

Message 133 - Msg rcvd for wrong node: Local =%d, dest=%d, sender=%d.

Explanation:

The local node received a message from a remote system that was not addressed to the local node. This is an internal znode error.

Action:

Contact your local HP representative.

Message 134 - LDM info rcvd for %d nodes; znode runstring only configured %d.

Explanation:

The number of nodes specified in the ZNODE runstring (-N <#>) was less than the number of nodes defined in the local TTGEN .answ configuration file.

Action:

Schedule znode with a larger parameter for the -N option, or reduce the number of remote nodes defined in the TTGEN configuration file.

Message 135 - Possibly remote node %d is running old, incompatible znode software!

Explanation:

The znode program on the remote node is not of a compatible revision with the znode program on the local node.

Action:

Update the remote node with the same version of the ACC products as the local node. (Note that the znode program is supplied with the ACC Base Software product as well as the X.25/ACC Bundled ACC product.)
