This is a snippet from the performance log on Jan 10 2002. Notice that
this script usually takes 0. some seconds. But one of these took 31.9
seconds. This happens periodically on our busiest sites. This file
only includes on file with a few functions. Executes two of those
functions. One just creates a menu using a few if statements. The
other simply outputs some html.
function stuff() {
?> html stuff here
<?}

I work for a company that has around 20 sites using PHP. Lately I have
been tracking some odd script timeout problems. None are related to bad
code or database connectivity.
I started doing some extensive logging and have a report that shows that
every timeout that I checked followed a pattern.
This is just a section of the log file I am looking at
Date Action # of processes running

The one that started first, finished last. That script usually takes
less than zero seconds. Though this time it took 60.014 seconds. Our
script timeout is set to 240 seconds right now so we can capture these
script durations.
This happens at all times of the day. No apparent pattern, other than
that the one that takes an extrodinary time to complete is consistently
the first one in this block of processes. And it always finishes last,
but that is less startling because it takes so long to finish.
