At 13:10:07 UTC (06:10:07 PDT) h1seiex went into an error mode:

Real-time code continue to run normally

Dolphin IPC channel data from h1seiex to h1iscex continued to run normally

DAQ data coming from the open-mx gigabit ethernet port to h1dc0 stopped running

The CDS network gigabit ethernet port stopped working (EPICS data, SSH login, NFS logging)

The console froze, no keyboard entry possible

The system continued in this state until  around 13:57 UTC when h1seiex was powered down. The system was fully recovered at 14:22:19 UTC (07:22:19 PDT).

The computer h1seiex has been running since the last site power outage of 06:08 Sep 30 2016 PDT. The SEI models have been running since the Dolphin glitch of 11:40 Oct 23 2016 PDT. In other words, this machine has not been running any longer than most other H1 front end computers.
