[LON-CAPA-dev] memory usage

[Mark Lucas]

I need some advice - 

	I'm running a trio of boxes that all have about 380M RAM a piece.

	After a hard night's work, these machines have httpd children that 
have bloated as high as 27Mb.

	I had to check the consoles for something else, and found that 
both my access servers had been killing off httpd children for lack of 
memory. I'm hoping it did this gracefully.

	I realize these are partially administration issues, which I'm 
supposed to know, but:

(1) What will kill off httpd children gracefully when they are DONE with
    handling a request? (I don't think I want to do a restart, that will 
kill off children without checking. Does reload actually restart the 
children?)

(2) I have a goodly amount of swap space, but unless I'm reading top
    wrong, the space is far from full, and the lonc,lond,httpd processes
    do not seem to be using it.

     Is there a reason for this???
