How do you know what is a good limit for file descriptors? Is their a way to see if my Squid is running out? I know how to find the limit but not sure if I have it set right. Does anyone know if CentOS linux requires a rebuilding of the kernel is the file descriptor is changed? I'm reading from Squid : The Definitive Guide about File Descriptors and I'm getting a little confused. I want to make sure I have this setup correctly on my new squid server. Brad
