I've got php 4.0.3pl1 compiled into apache 1.3.14. It seems to work fine, except that at intermittent intervals, on loading a .php page, I get a "the document contained no data" error. Usually, if I reload whatever page or frame gave the error, it comes up just fine. So far I only see it on .php documents, but other than that, I've found no pattern.
So far all of the 'document contained no data' help I've found online involves core-dumps, bad cgi environment setups, and such which cause consistent cases of this error.
Can anybody give me any hints as to what might be causing an intermittent error like this?
