hitting the limits

Hi Folk

I am managing a site, www.friars.co.nz that seems to be hitting the limits
and I keep getting the 500 error. According to the people from webfarm it
is because my script are too demanding or not closed properly.

I dont believe you have to "close" PHP scripts or even database connections.

The site also accesses a 80 Megabyte database.

Do you know of a way I can find out where the problems are or improving the
performance of the site?

I uses ob_start and ob_end_flush, would that cause problems?

TIA

Nicolaas
