Forum OpenACS Development: More on lost of memory of aolserver process

(This message is also sent to the aolserver maillist.
Sorry by the duplicities)

Down there is a small extract on the memory behavior of the Web server
(time / mem in KB) in our production server.

Hardware is:
-Opteron 64 dual
-4 GB RAM

The software scene is:
-Linux Debian AMD-64 Sarge
-aolserver-4.0.10 (http and https)
-tcl8.4.11
-OpenACS 5.2 with dotLrn
-Many concurrent conections.
-Postgresql-7.4.8 (in other server)

I think of I have applied all the patches I have seen in this maillist.
(The behaviour is the same that in 32 bits Debian)
HTTPS is not the problem. TCL is not the problem. It is a production server
and I think of is very complicated put it in mode debugger.

Any pointer to detect where the memory is losing?
To this rate of loss the server (from 1 - 10 MB per minute) only holds 2 days
of uptime.
