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.
