Hi all,
I've noticed that I have a memory leak under Ubuntu Lucid. I am
running a quad core Opteron with 16 Gigs of ram, 64 bit OS with
clients built with i386 option. Everything
starts off fairly well, but within a day or two I've used up nearly
all of the 16 gigs. Right now, with a four days of uptime and only 5
users on the system, free shows me only 2 gigs left but I don't see
anything
crazy using top. This problem has persisted accross kernal upgrades.
Output from uname, free, and top pasted below. Any ideas how I might
track down the what's going on?
Your advice would be appreciated.
John
