I nearly cried when I took that machine down.
I know what you mean. I always feel like I'm shooting my dog when I have to bounce the system. Right now I've got a game server suffering a couple of WINE zombies because I don't want to bounce it. I had to move the replacement processes to new ports.
I bounced a server the other day with 96 days uptime because FC2 released a new 2.6.9 kernel, and that server was one that I could afford to test it on. (There's a WINE issue with 2.6.9 involving changes to ptrace that Linus only recently fixed.)
