hose errors you're seeing are outgoing connection attempts
 so there a few things to check...

What version of pjproject are you running?  There's an issue in 2.4.5 and
earlier where TCP sockets aren't being reused
.  It's fixed in their trunk.  Unfortunately, you can't use their trunk
with Asterisk 13.7.2 because of a new api they introduced.  You'll have to
use Asterisk's current 13 branch from git.  If you 're going to do that,
check out the bundled pjproject option which also has that patch.

Check that sipp isn't terminating early and forcing Asterisk to open a new
connection just to send the BYE.

How many connections are you attempting?

If you really want to get the max connections, set the --enable-epoll
option on pjproject's ./configure line (assuming you're on Linux) and
set PJ_IOQUEUE_MAX_HANDLES
to 5000 or something.  This won't fix the connection refused messages
however.
