Re: Re: fopen() for http:// sometimes working, sometimes not

If it's a busy server, you may be running out of TCP connections... If PHP can't open ANY connection at all, it can't do a DNS lookup, and it would fail very fast, as it's hitting an OS limit/cap on the number of connections and not even getting to try to talk to the Internet.
