No no .. you should not disable swap partition.MMlosh wrote: Do you think that disabling swap partition might change anything?
What I've disabled is a mechanism like a per-process control over the swap allocation : if you want to test if this could solve the problem , just add the option "noswapaccount" the the boot commandline.
If you are not used to modify boot commandline and or reconfiguring/recompiling your kernel , just ask for support to the ubuntu forums.
