i am using my laptop with PHP 4+ and mysql 5+, everything start to be weird
after i implement my costume sessions (storing in database).
i only use one database connection for the whole website.
what i mean is, the session and every query connect to mysqlserver using the
same user.

I am not sure if it is because of the sessions. but it happen after i use
costume sessions.

if i make a SQL query with non existant column name eg: noe

SELECT * FROM test WHERE noe=1;

Suddenly, if i use top to monitor process on my laptop i saw the processor
usage for the mysqld and firefox-bin(iceweasel) increasing.
Icewasel will continue to consume processor usage to 100% and memory up to
80% all the time.

Worst still, the mouse, keyboard do not work anymore. My laptop very-very
slow until i cannot move my mouse cursor at all..

there is no way i can go except turn off the laptop power.

I don't know what the problem is this. but, i think there is something to do
with the sessions. And it related to PHP or may be problem with Iceweasel.
I will try to ask debian mailing list for this.

In case anyone experience the same thing. please let me know how you fix it.

Show us your source for the session queries and any loops that
surround that.

Most likely, you have an error in there.

Or, even more likely, you have a:
header("Location: ***");

where *** ends up putting you back on the same page...

Then you execute header("Location: ***") again.

This puts you back on the same page.

Then you execute header("Location: ***") again.

This puts you back on the same page.

Your browser and your server (which are both on your laptop) are stuck
in an infinite loop of header("Location: ***") re-directs.

Don't do that.
