I have a curious issues. I run three servers currently, 2 are dedicated machines, and am enjoying the unixshell xen vm.

However, when I ab -c 10 -n 10000 my machine I start getting socket timeouts reliably after around 6000 connections.

I'm not concerned with how fast I can serve web pages, but just that things will stay up over time.

Checked open file descriptors, log files for error messages. Nothing

Exact same description on other systems just go and go.

Is there anything as part of the network or elsewhere that triggers based on a flood of connections from another host? I'm not sure what other types of trouble shooting options I've got.

You'll probably find more answers by posting to the xen users mailing list.

Depending on how much RAM you have you probably just run out of memory for the network buffers... on a 32 or 64 I would say that is definitely it.

Matt was exactly right...

No surprise there, the math checks out. I'm dumping a dedicated development machines for unixshell.
