Well, I thought I'd have some forking fun. Its seems that my university computer doesn't have process quotas turned on...
This lead to some interesting uptimes,
2:42pm up 45 day(s), 21:30, 2 users, load average: 0.18, 0.43, 0.39
2:42pm up 45 day(s), 21:30, 2 users, load average: 19.76, 1342.68, 1231.63
Again, I'd like to say "Whoops" I really did think process quota's were running. On the plus side, Solaris recovered pretty quickly :-)
