The version we got this crash is almost the same as the current head of the 8.1.x branch.

Also take a look at PR #7397. That one just fixes things so traffic_manager gives up after failing to open the cache disks.

It looks like ATS found a bad disk and tried to delete it, but got SEGV on `disk_vols[i]->dpb_queue.pop()`.

About 6 months ago, I spent many iterations trying to fix our crash on bad disk problem. What version are you running? I thought I had pushed those fixes to master.

Take a look at PR #7218. I thought I had to make multiple attempts here, but this is the only relevant looking PR I see on master. I'll review my internal work and make sure it all made to to ASF. It could be that I delayed making an ASF PR until we got it all under control.
