[mythtv-users] Possible Memory Leak?

[Ken Thompson]

I read your message yesterday Isaac.  Thank you for all your help, I'm
really a total linux newb.  Tonight I'm finishing up my reinstall of
Mythtv (the second time is always cleaner) and I will do more extensive
testing on its memory usage.

If it were a memory leak in mythtv, killing off the process would free
the 
RAM.  Leaked memory in a userland application doesn't stick around after
the 
application is gone.

As I posted yesterday, but apparently no one read:

To get the _real_ amount of ram that's used/free on a system, run 'free'
from 
a command line, and look at the -/+ buffers/cache line.  The top line
(which 
is what is reported by 'top' and pretty much every system monitoring
app), 
includes all your internal kernel buffers, etc, that are freed as
necessary.
