--- Comment #19 from Craig Leres <[email protected]> --- Today was my third hang in a week, second day in a row. I had several windows on the box and tried to do a live savecore; that got into D-wait pretty quickly. Soon almost anything I did would hang (including the sysctl panic). Is there a problem with the way I have swap configured on this box that is preventing savecore from working? This server runs zfs on six nvme drives. zinc 7 % dumpon -l mirror/gm0p2 zinc 8 % gpart show => 40 937703008 nda0 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) => 40 937703008 nda1 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) => 40 937703008 nda2 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) => 40 937703008 nda3 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) => 40 937703008 nda4 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) => 40 937703008 nda5 GPT (447G) 40 1024 1 freebsd-boot (512K) 1064 984 - free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 870590464 3 freebsd-zfs (415G) 937701376 1672 - free - (836K) zinc 9 % gmirror list Geom name: gm0p2 State: COMPLETE Components: 6 Balance: load Slice: 4096 Flags: NONE GenID: 0 SyncID: 2 ID: 859694810 Type: AUTOMATIC Providers: 1.
