Bob,

We have not experienced system memory leak problems on our RedHat 7.3
systems.  We do, however, see that the free memory listed in 'free' or
'top' apparently drops to zero.  We believe hat the OS is using free
memory as a disk cache, but will give it up when needed.  This doesn't
seem to affect swap space.

What exactly are you seeing?

We are not yet running RedHat 9 in-house here at the UPC, so we would
not be able to help you with problems if/when they occur under this OS.
