0 MB free swap and 1920 MB swap in use.
Like I said the last time this came up, you will want to continue increasing your memory until there is only 0 MB to 50 MB swapped. The other option is to use software that uses less memory. It's not a connectivity issue, it's your VPS is grinding to halt because you're trying to fit too much software into too small of a box. Try to imagine a 30 pound cat trying to fit into a 4 inch box. That's what you're doing to this VPS. If you want to increase the memory as a free trial for a few days to test it out we can do that.
