Problems installing OpenX 2.6

[nicksnels]

Hi,

I'm trying to install OpenX 2.6 (www.openx.org) on my server. I get to the installation step where OpenX lists all the directories in which it is going to save its information. When I go to the next step I would normally configure the admin password, but all I get is:

503 Service Unavailable
The server is temporarily busy, try again later!

In my error.log, I have the following entries:

Is this an OpenX, Litespeed or PHP matter? Any help is welcome. Thanks.

Kind regards,
