While running several Wallboards, maybe connected to several queues, it is not uncommon to see a shortage of ephemeral ports. You can count how many ports you are using with AMI with the following command:
netstat -an | grep TIME_WAIT | grep -c :5038
Common solutions would be to lower your TCP timers and turn on tcp_reuse. In your sysctl.conf file, add:
net.ipv4.tcp_fin_timeout=1 net.ipv4.tcp_tw_reuse=1
