Hi,I'm using XEN with gentoo base systems. Both the domain-0's and the domain-X's are gentoo. I build my gentoo systems according to a script, and they are all identical, save for things like hostname, IP, user content, etc. So here's my question/problem: I have some 10 "Regular" or conventional gentoo servers.Then I have around 8 Xen based servers most of which have 4 domain x's on them. These machine are all the same - dual pentium 4's, 2G ram, intel 865g chipset, big drives. Okay, so the regular or conventional servers use ram and swap as expected - they allocate and deallocate swap as needed and I have uptimes on the order of 185day avg before I do a kernel rebuild or something. On the xen machines, i HAVE TO reboot every 25 - 30 days because they NEVER deallocate swap usage and eventuall use 100% of the swap and also ram and then lock up hard if I don't reboot the machine before it gets there. I can't use swapoff and swapon again - here's the error I get: server1 / # swapoff -a swapoff: /dev/sda2: Cannot allocate memory this machine, server1 has been up some 25 days now: server1 / # w 15:25:41 up 25 days, 3:36, 1 user, load average: 0.16, 0.13, 0.09 USER TTY LOGIN@ IDLE JCPU PCPU WHAT root vc/1 22Jun05 1.00s 0.04s 0.00s w and our memory allocation is getting high: server1 / # free -m total used free shared buffers cached Mem: 441 433 7 0 13 159 -/+ buffers/cache: 260 180 Swap: 964 582 382 I'm using xen-2.0.4 with kernel 2.6.10 Does anyone else have this issue, and what have you done to resolve it?
