Hello,

I have an two of four Elements Timing out , I see  Stream Viewer shows an "Undefined" group ~ Redundant Polling, change connection

I compare side by side timing our and not timing out element / stream viewer windows and see the following undefined group with the following messages

RedundantPolling, change connection, entering 1 RedundantPolling, change connection, leaving 1 RedundantPolling, change connection, entering 0 RedundantPolling, change connection, leaving 0 RedundantPolling, change connection, entering 1

Elements are running same protocol version, devices are running same firmware, nothing has changed, all four were connected until we started noticing timing out. Ive tried duplicating and assigning the element to another DMA but issue persist. Ive checked firewall rules and nothing has changed all SNMP traffic is allow.

Heres a screen shot of groups side by side

To update this thread,

we found the issue may have been related between IPX and Magnum. Not sure why when the cache in magnum is full stops snmp traffic or at least as it deletes/gets hits threshold the element timeouts/connects. During our maintenance window we cleared the cache in Magnum and rebooted the IPX. This restore snmp connection to the device.

We never changed protocol.xml file and we are running latest version available for the IPX.

Also we looked at configshell logs between the devices and see immediately there was no SNMP traffic.

This led Evertz too look at cache as possible culprit for the loss of traffic.
