As I saw the thread today, I started looking at it myself, on RH's
 2.4.18-18.8.0. By now I have:

 1  0  0 432892  23828  44648 407208   0   0     0    24  780   879  95   5=
   0
         =3D=3D=3D=3D=3D=3D

However, top says:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
 1450 dmitri    15   0  546M 178M 16212 S     1.1 23.6  21:50 pan

I close pan, and what a change!

 3  0  0 432664  20720  44748 410260  88   0   392    20  710   925  95   4=
   1
 1  0  0  46316 197172  44760 409684  40   0    40   160  782  1177  88  12=
   0

So you probably still have some process which is eating your memory. And
once you find it, restart it:

  PID USER     PRI  NI  SIZE  RSS SHARE STAT %CPU %MEM   TIME COMMAND
 3994 dmitri    15   0 15044  14M  6152 S     0.9  1.9   0:00 pan
