3.4.0 Matrix Server Administration Guide

Appendix B: Error and Event Log Messages 240

PanPulse should receive matrix traffic at certain intervals on the active

administrative network interface. If PanPulse does not receive any traffic

during this period of time, it will report the following message:

No traffic received on active panpulse interface (<ethn>)

PanPulse then fails over the active interface to another network interface

and reports the following. (You will also see this message for other

situations in which PanPulse chooses a new active interface.)

Selected new active interface <ethn> address

<xxx.xxx.xxx.xxx>

If PanPulse cannot communicate with all other active servers over a new

interface, it will report the following message:

Unable to fail over to another interface

Network Interface Requirements Are Not Met

PanPulse generates error messages when the requirements for a network

interface are not met.

IPv-4

Only IPv4 is supported. If another address family is specified for the

network, PanPulse will report an error such as the following:

Interface <ethn> has addrtype AF_INET6, skipping

Port 8940

Only one instance of PanPulse can be running on port 8940 on a server. If

another application is using that port or another instance of PanPulse is

started, the following error will be reported.

Unable to bind on port 8940. Please make sure that this is

the only copy of panpulse running on this server.

Fence Agent Error Messages

Fence Agent error messages are typically caused by operational problems

with a FibreChannel switch, a loss of network access, or an unresponsive

switch. For CISCO MDS FibreChannel switches, errors can appear if the

default VSAN is disabled.
