Dying Dock

My dock keeps dying. Repeatedly. Over and over.

Only solution so far:

ps -vax | grep -E "Dock|PID"
kill -HUP PID
kill -s SIGCHLD PID


And similarly for problems with Chrome + /usr/sbin/mDNSResponder. They tend to go bad together.... no clues yet from the system logs. Ironically, the crash reporter seems to fail the most often...
