Sorry for the delay on this one but it was a very nasty bug to solve.
After a few tries, we have isolated this to a kernel problem. Took a lot of time because the logs were clean: no clues, no traces... nothing.

The problem was constant lost connections to the mysql server. These caused the mysql_num_rows errors in every file that used them. I've kept my changes for the times mysql_num_rows was used to count rows. The COUNT(*) function is better.

As soon as I know anything else about this particular kernel issue, I'll post here. Maybe it would be helpfull for someone.

Anyway, my apologies and thanks to everyone that lost time with this issue but unfortunately this was beyhond my control =(
