I'm sorry my english... I need increase file descriptors in RedHat 7.3 kernel 2.4.18, I modify ulimit and sysctl parameters (fs.file-max = 4096, fs.inode-max = 16384), but in squid rpm package don't increase value of file descriptors: Starting Squid Cache version 2.4.STABLE6 for i386-redhat-linux-gnu... Process ID 676 With 1024 file descriptors available How I can increase file descriptors ? Regards,
