Greetings, I hope you can help me solve this problem since the only way I can solve it is by restarting the platform.
could not connect to ethash pool PhoenixMiner -epool eth-eu1.nanopool.org:9999. An operation on a socket could not be performed because the system lacked sufficient buffer space or because a queue was full
the error appears every 20 hours and the only thing I can do is restart
Sorry my bad english
more information is required, which operating system, how much memory is in the system, is the amount of virtual memory increased, how many video cards are running, all the contents of the batch file
no more information is required.it is not related with virtual memory or bat file. this error maybe is virus or bug when you run 2 bat files at the same time. ports are not closing after devfee mining then it connects 2nd devfee then 3rd then 4th finally it runs out then you get this error.
I can run 2, 3, 4 instances of phönixminer at the same rig. So i think you make a mistake.
You say it is the port, but you say you have disabled your firewall, so how it can be the ports?

i think it is your virtual memory, but without any information about your system or how much cards and so on.
