Re: After retrieving data from DB, the memory doesn't seem to befreed up

Hi,

I think you got me wrong.

My initial question was basically something like "how could I preserve/give 
back memory if needed" (i.e. in rare situations) and the reply turned up 
into a "don't use large scalars". (which is relevant, I agree, but was not 
directly replying my initial question)

Unfortunately, I am developing under Windows, so...

Here, as well, killing a child process under Windows, means killing my whole 
Apache server (and so all the serving threads).

So, that's out of the equation.

I thought that $r->child_terminate would work under threaded MPMs as
well, but it doesn't.

My mistake.
