MySQL Error Code 10055:
This error actually indicates a problem at the operating system (OS) level rather than a MySQL error.
Windows uses a random high range of dynamic ports. What is happening is there are not enough ports to facilitate the request.
Increasing the amount of ports will effectively resolve the problem.
Release: Spectrum 10.2 installed on Windows 2008
netsh int ipv4 set dynamicport tcp start=10000 num=50000
netsh int ipv4 set dynamicport udp start=10000 num=50000
Spectrum does not use IPv6 for this but we can increase those ports as well while we are at it:
netsh int ipv6 set dynamicport tcp start=10000 num=50000
netsh int ipv6 set dynamicport udp start=10000 num=50000
