vzstop stop --fast - behavior crashing box

[dlasher]

problem: shut down Proxmox (which shuts down containers via "vzctl stop 103 --fast") and the box will crash with a kernel hang.

if you ssh/vzctl in, and shutdown the container (either with a shutdown -h now inside the container, or a NON-fast stop from the pmx CLI), then shutdown the box, no crashes, everything is fine.

from the log you can see the symptom:

The 103.stop file tries to umount the directories mounted into the container, but the --fast doesn't wait long enough.

How can I either remove the --fast option from the GUI driven shutdown, or resolve the actual problem?

103.mount

#!/bin/sh
mount -n --bind /raid/myth/livetv /var/lib/vz/root/103/myth/livetv
mount -n --bind /raid/myth/tv /var/lib/vz/root/103/myth/tv
mount -n --bind /raid/myth/video /var/lib/vz/root/103/myth/video
mount -n --bind /raid/myth/music /var/lib/vz/root/103/myth/music
mount -n --bind /raid/myth/gallery /var/lib/vz/root/103/myth/gallery

103.stop

#!/bin/sh
sleep 20s
umount -l /myth/tv
umount -l /myth/video
umount -l /myth/music
umount -l /myth/livetv
umount -l /myth/gallery
sleep 10s

Anyone else on the forum seen this issue with bind mounts into containers? several of my friends also run ProxMox, and they're seeing this as well.
