WinNT 4 SP6a, all of the latest patches (yea, yea I know). PHP 4.3.1 I
am getting 1,2,4, or more process instances of PHP running using 100%
CPU. Cannot narrow it down to bad programming code by users or a php.exe
problem. Most PHP is running fine. I have a few PHP forums running. I
cannot reproduce the problem, but it is increasing. Concerned that it
may be a attack. This is now occurring 4 or more times a day. Only
option is to kill the errant processes. Sometimes a reboot of the server
is mandatory. After killing the processes, normal PHP code in our forums
runs fine. There are not any consistent instances of PHP runing in the
background unless this problem reoccurs. The PHP.INI is set as follows;
max_execution_tim = 30; max_imput_time = 60; memory_limit = 8M . It has
now effect on this problem, we have seen it run over 4 hours without a
sign of stopping on its own. I don't have the memory usage noted, there
is not any unusually high traffic across our network during the
instance. Most dynamic pages fail, only static pages are served from
IIS, due to the high CPU load. PHP request run, but very slowly as do
all request during this time.
