Utility crashing entire OS.
One drive failed in the array. I never got a warning from the Utility, despite being set to the lowest setting for warnings. I just happened to notice that one drive light was red.
I replaced the drive as usual, and it powered up as expected and was seen by the computer in System Report, but Promise Utility would launch with all menu options were grayed out, and the main interface window never appeared. Utility indicated all software and firmware was up to date.
I tried re-installing the utility, and since then, every time I launch the utility, it crashes the entire machine. Partial report from Console.app below.
After an entire day of tryng everything I could think of (reinstalling the utility, driver and DEXT DriverKit file, etc) I was finally able to get the RAID volume to mount... I have no idea how or why, but I'm cloning it off to a competitor's RAID immediately.

Pegasus R4. (I had migrated to a Peg32 until it totally died, right after sending it to Promise just before the warranty expired. I had demonstrated that it was an inconsistent problem, but they said that nothing was wrong. This response came so quickly that it's pretty clear they just plugged it in once, it mounted, and they diagnosed "user error" instead of doing a proper test on it, knowing that if they delayed the repair, it would go out of warranty. It continued to unmount and/or refuse to mount and/or refuse to restart without unplugging the power cord. Very quickly after that, out of warranty, it totally died and will not power up at all, but I'm too disgusted by the lack of support to even repair it. Well over a decade of owning & recommending Promise products, and now every time I walk into an edit suite and see one, I recommend changing to another brand as fast as they can.)
