When failure occurs, which initially was within ~30 minutes of rebooting "R" core, "R" core's votes are thrown out and missed vote counters will accumulate rapidly in the diagnostics missed votes section for R core.
All cores have been inspected (card status) and found at A7 prior to rebooting; then all cores are rebooted and reach A7 status again. During the reboot of each core, no outstanding flags are noted except I did see "R" register I/O board failure. This appeared to clear upon completion of reboot.
All power supply values are stable.
Immediately upon total reboot the unit has "ready to start" status which would last for about 30 minutes. During this good status there were no notable alarms coming in. P62 (common I/O comm loss) and P249 begin to toggle alarm-normal-alarm, etc. sometime during the 30 minute good status. Note: master reset will not reestablish ready to start; this has only been achieved by rebooting the "R" core.
TCQA, TCQC boards and ribbon cables have been changed along with eeprom swap to the new cards along with MK5 makes; failure time stayed at ~30 minutes.
Next, the power supply board for R (located in the back of core) was replaced. The "ready to start" status then lasted for about 1 hour.
Lastly, the LCC board was changed and ready to start status lasted for eight hours before failure.
Any help is appreciated. Thank you.
