The two machines are at 98 and 138 days uptime, and both are currently using more than 90% swap, and I've had to shut down non-critical stuff because I was getting out-of-swap errors. Just wanted to let everyone know, since I haven't seen any revisions as early as r325275 in the "me too" posts here. More information available on request. Best regards, Thomas Steen Rasmussen
