Attached plot shows CDS overview after the crash (13:56 PDT). Things to note: h1susauxex has no problems (this is the only machine without a Dolphin card at EX), most user models stopped running except for h1susetmxpi, h1isietmx, IOP models are running but with DAC/DK errors.

At EX I noted:

No activity in the building around the time

No timing issues on any IO Chassis

Computers have been running for close to 8 days (since 16:00 Tue 18th Sept PDT)

All models not running reporting ADC timeouts in dmesg. Details below

computer model adc timeout parameters
h1seiex h1hpietmx ADC TIMEOUT 3 40582 5 40646
h1susex h1susetmx ADC TIMEOUT 0 39380 20 39444
ditto h1sustmsx ditto
h1iscex h1iscex ADC TIMEOUT 1 39571 19 39635
ditto h1alsex ditto
ditto h1calex ADC TIMEOUT 0 39571 19 39635
ditto h1pemex ditto

I checked all front end computers could see their IO Chassis. I then restarted all the models, no reboots were necessary.

I've opened (and immediately closed) an FRS
