[comp.sys.amiga.tech] Lost memory

brindley@ECE.ORST.EDU (Mike Brindley) (12/18/90)

My A3000 just arrived late last week, and I noticed something odd in the
free memory display on the top line of the WB 2.0 screen. Basically, I
open a drawer, look at it, close it, and the free fast RAM (other) doesn't
return to the value it had before I opened the drawer.  It comes up with
a smaller number; it appears that my machine is losing memory!  Here is
an example sequence of actions from power up:

Action                               Graphics mem     Other mem
---------------------                ------------     ----------

Power up                             945480           248640

Open Sys 2.0                         934400           237512

Close " "                            945480           248088    (Lost!)

Open Work:                           941872           242904  

Close Work:                          945480           247032    (Lost!)

Run NComm, quit,
return to just WB open               945480           240680    (Lost!)

As you can see, the graphics mem returns to its original value, but the
'other' mem is reduced.  Some of that may be taken up by extra system
things being loaded (serial port hander, buffers, perhaps?), but just
opening and closing WB drawers should not result in any lost memory.
In playing around with the system, I have returned to just the WB  
screen and found that i had less than 100K other mem free!

Is this an actual problem (i.e., after a long day of windowing around,
will programs refuse to run/crash because they don't have enough memory?

Thanks,
