Perhaps there is some issue with the kernel's network stack, and it
could be resolved by trying a different version. 256Mb of ram should be
able to handle a lot more than 600 connections (they consome 100 or so
bytes each). That is, unless your box is very low on memory for other
reasons. I've done tests with LVS going up to 3,000,000 connections,
on boxes with around 512Mb or ram (I don't remember exactly), so it
shouldn't be an LVS problem.
