Re: Re: Really odd PHP problem... different platform

A large telco client of ours is having problems that match Russ' problem almost exactly... except on Win2k. Does anyone have pointers to *windows* tools to achieve the kind of debugging/tracing described below? Rasmus Lerdorf wrote:

I can watch them for hours in the apache mod_status view, and they'll show the same last request. They won't respond to a kill -15, I have to kill -9 them. Strace reports they're doing absolutely nothing.

Could you use 'gcore' to drop a core from one of these spinning processes and get a backtrace, or simply attach gdb to one of them and see if you can get a backtrace. Chances are it's off in the middle of nowhere, but by poking around a bit and looking at 'ap_request' and walking through 'ap_request->headers_in' you should be able to get an idea of the exact request that caused it to go nuts. -Rasmus
