Fact One: File Descriptor Limits Friends who write network server programs in Linux surely know that each TCP connection occupies a file descriptor. Once this file descriptor is exhausted, a new connection attempt will return the error “Socket/File: Can’t open so many files”. At this point, you need to understand the operating system’s limit on … Read more
