Having a very frustrating problem and I can't seem to figure out why
it's happening.
1. As of last week, all of our applications have started to work
intermittingly. The codebase has not changed.
2. Sometimes the application will display, sometimes it won't. The
browsers "loading progress bar" will move for about 25% then just
stop. No timeout or 401 errors occur.
3. There are no errors message in any of the logs files.
To test if it's our application we have done the following in our main
php file which runs the rest of the application
<?php
echo "Step 0 <br>";
--Segment of our code is here--
echo "Step 1 <br>";
--Segment of our code is here--
echo "Step 2 <br>";
?>
Sometimes it doesn't even get to the first line of php code which is
the first echo statement, sometimes it gets to step 0 and step 1 and
sometimes it gets to all steps.
The code between each of these steps is nothing major, nothing calls
mysql or anything like that. It's mainly just variable initialization.
Again, the entire application runs fine every couple of refreshes.
Then sometimes it'll just stop completely. I have turned on all sorts
of debugging and nothing.
I have reinstalled apache, mysql, and php 2 times. We have also
optimize both apache and mysql for for than enough client connections
as well are using persistant db connections. But like I said, the
application works sometimes, sometimes it doesn't. And the data is
pretty static.
I am running RHEL 3 U3 with RH php version php-4.3.2-19.ent, RH mysql
server version mysql-server-3.23.58-2.3, and RH apache version
httpd-2.0.46-44.ent
Thanks guys for any help troubleshooting this.
