Mike, it is the memory management of the operative system the part
which releases memory. One of the bad problems with Windows is that
once you close an application, it never gains back the full memory
"block". This is a well known Win problem since ... 2000 years ago :P
If you start up & close down applications 10 or 20 times/day, you may
end up with memory gaps of up to 500 Mb (out of 1 Gb RAM). To avoid
this, I use CleverCachePro which is a memory management program that
solves all of these shortcomings. Also, it makes up a (dynamic or
fixed) cache out of part of the RAM where it loads applications which
you load up frequently - making the system faster.
I dont even get craches during "blow_up_the_box_simulations" - a
"Marine kind of field testing" I do sometimes to see if the box will
do the job. Without a good memory management, the box will crash.
Another problem could be that you have some tiny program loaded into
RAM which doesnt respect the memory addressing and will crash your
system.
Cheers!
