What's your definition of long-lived? My scenario is that I'm processing
a particular dataset in Python which is launched by a shell script, once
finished (after 30-35mins) the Python app completes and the shell script
launches another instance on a new dataset. All memory allocated by the
finished Python app should be freed/made inactive shouldn't it?
Here's some more data:
After a reboot this is what top says:
Mem: 45M Active, 13M Inact, 61M Wired, 4K Cache, 60M Buf, 2842M Free
Swap: 4068M Total, 4068M Free
which totals 3021M
After 1 dataset it is:
Mem: 107M Active, 1919M Inact, 158M Wired, 16K Cache, 214M Buf, 570M
Free
Swap: 4068M Total, 4068M Free
which totals 2968M
While running on the 6th dataset:
Mem: 1032M Active, 1045M Inact, 260M Wired, 145M Cache, 214M Buf,
4664K Free
Swap: 4068M Total, 108K Used, 4068M Free
which totals 2700.6M
Are my assumptions incorrect, should the totals displayed by top be at
least approximately equal?
