Thanks to Dr Blinn, Pham Zoong, Dan Harrington & David Ross.
All suggested that there is nothing to be worried about. This is an informational message letting us know that there was a queue at the tulip ethernet interface (tu0) that was restricting the delivery of packets. The software had simply increased the size of the buffer and was letting us know.
HOWEVER, seems that there is a problem on the LAN that these machines are on that is causing high network activity and causing a bottle neck at the switch port that the tu0 is connected to. This is what caused the ase messages.
This part of the problem is still being investigated.
See below for original call.
Thanks

Hi all,
Have had this error message this morning on one node of a DS10 cluster running V4.0F patch kit 7.
tu0: transmit FIFO underflow: threshold raised to: 512 bytes
This coincided with an ase message received;
HSM ***ALERT: HSM_PATH_STATUS:192.168.4.42:UP:10.15.253.235:DOWN
HSM ***ALERT: HSM_PATH_STATUS:192.168.4.41:UP:10.15.253.236:DOWN
HSM ***ALERT: HSM_PATH_STATUS:192.168.4.41:UP:10.15.253.236:UP
HSM ***ALERT: HSM_PATH_STATUS:192.168.4.42:UP:10.15.253.235:UP
The outage lasted 1 minute 13 seconds. Too long by half.
Has anybody seen this before and perhaps could shed some light on it for us. Does it mean a parameter is incorrect? Could it be the network switch is flackey?
Any help would be greatly appreciated.
