Echoing source to browser -- Bug?

I'm having a very peculiar problem on my machine with the latest CVS version of PHP4. Everything is running perfectly fine, but every now and then it seems as though Apache isn't invoking the PHP parser, it's just echoing the source to the browser. If I restart the server it begins working normally again, but unfortunately I have not yet been able to isolate the behavior when running apache in gdb (of course, I wouldn't even know what to look for if that were to happen!) I'm wondering if this has happened to any body else? Could this be a problem with apache? I hadn't received any warnings when compiling/installing, and it seems to happen quite frequently (at least once a day, especially when the server hasn't had any use for a while). Thanks in advance for any help/advice. Peter -------------------------------------------------- Peter D.
