socket: Too many open files (24) apache bench lighttpd

When I start Apache Bench test:

ab -n 10000 -c 1300 http://domain.com/test.php

I get error:

socket: Too many open files (24)

When i change to '-c 1000' it works fine.

Because I can have more than 1000 concurrent users I would like to fix socket too many open files problem or increase parameter. How to do this and where?

I use lighttpd on centos 5.
