Just to update for those interested. There may be a problem with the current upgrade 0.6-203@210512.
Yesterday the same thing happened around 11am. My CPU LA surged to approx 9 and caused the rig to crash while I was away. I was able to get to restart but only after about 40 mins of down time. When I got back to my office. I decided to revert back to the previous version os.
The current version was 0.6-203@210512… I selected the nearest reversion @210401… and it downgraded me to 0.6-202@210512. At first glance it looked like the “current” version… but it has one number different… the 2 in front of the @ sign.
Since the downgrade, the rig has run smooth for 18 hours. I will keep track of this.
Seems there may be a problem with the current os upgrade.
FYI… my rig is running AMD cards… only.
