Console was non-responsive. This time dump locked doing /usr so pretty much anything you try to run will block. When the lockup happens when dump is running on my home dir (/u/yertle1) partition, as long as you don't need that partition you can log in and run any programs you like. I have a service account whose home dir is in / var and was able to login that time to that account. No such luck this time since any activity pretty much uses /usr. Ping was responding (our monitoring didn't complain it was down). The only thing I could do was break to debugger on the console. --Apple-Mail-6--786442767--
