That's getting close to the limit.  Usually only high-numbered ports
are used for outgoing connections.  Since you mention you are running
Linux, you may wish to check /proc/sys/net/ipv4/ip_local_port_range
and possibly widen the range to see whether that helps.  E.g., the
default range on my system appears to be 32768--61000, which allows
at most 28232 outgoing TCP connections that are not bound to specific
ports, and fewer if some of the ports are stuck in wait states.

/proc settings (as you are probably aware) are usually changed using
echo and shell redirection, so you would use

  # echo 24576 65000 > /proc/sys/net/ipv4/ip_local_port_range

or a similar command.
