I am running macOS High Sierra 10.1 3.2, with latest update on a 12 core Xeon Mac pro from 2013, – the trashcan

I have high Kernel activity of 20-30%, high temperature with the fans running.

If I disconnect the RAID array this all stops and activity is less than 5% doing normal tasks with Word, PowerPoint et cetera. This is my usual level of activity,

I have updated to the latest firmware and the latest version of the Promise software (4.0)

Disk utility and the promise utility both report the array has no problems. 

I wrote about 350 GB of video data to the array which seemed to start this. This is unusual for me and there is still 5 TB of free space. 

I have excluded the array from spotlight indexing, – it has no effect.

Hi, 

I'm having exact the same problem as stated above. My Pegasus has been running smoothly for four years and now it crashes my system more than ten times a day. If I disconnect the R4 everything works fine. Copying files takes ages, it constantly freezes up. After a restart the fault and slow behaviour comes back after a while.

What´s wrong? How do I fix it?
