High use of cache memory
Hi,
I'm running a debian lenny 1GB ram, but with a high I/O. This server has 400IOPS and 3MB/s sustain. So, I noted cached memory use 800MB, buffered memory use 50MB, and no free memory is available. Questions:
What does mean such a high cached memory?
Who's using this cached memory?
Is it normal this high cached memory?
thanks in advance
regards,
Israel.

define_cached_server
define cached server(1m) define cached server(1m)
NAME
define cached server - Creates knowledge of a server in the local clerk's cache
SYNOPSIS
cdscp define cached server name tower value
ARGUMENTS
A simple name for the cached server. The protocol sequence and network address of the server node. The format is protocol-sequence:net-
work-address. A protocol-sequence is a character string identifying the network protocols used to establish a relationship between a
client and server. There are two choices of protocol sequence, depending on the network address that is supplied in the binding:
ncacn_ip_tcp or ncadg_ip_udp. For the network-address, specify an Internet address using the common Internet address notation. For more
information about this format, see the RPC introduction in the DCE Application Development Reference.
DESCRIPTION
The define cached server command creates knowledge of a server in the local clerk's cache. This command is typically used to manually pro-
vide configuration information to a clerk that cannot automatically configure itself. This is required, for instance, to give the clerk
addressing information about a server across a WAN. Once the clerk knows about one server, it can find other servers through referrals.
Privilege Required
You must have write permission to the clerk.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and may not be provided in future releases of DCE.
EXAMPLES
The following command creates knowledge of the server nrl in the local clerk's cache: cdscp> define cached server nrl tower
ncacn_ip_tcp:16.20.15.25
