The database collapsed. Seems we make use of it in some way that it didn't like. As such I have reverted to the originals and it should be functioning a bit better. I'll use the stack dump and logs to send to the author so he can fix it, but I THINK its probably to do with the huge IN list that we use in some of our queries (that is, select * from fred where uid in ( 1, 2, 3, 4, x, x, x ); )
Sorry for the days troubles... Believe me I am :-)
Steve.
