How much men does the router have on it?

Hi,
I have a 2811 router running Advanced IP Services 12.4(19) which has
been acting funny.
First issue I had was after inserting (2) WIC-1ADSL cards the
processor jumped to 99%. After shutting down the interfaces and
rebooting, the router went back to normal.
Now the router is becoming intermittently inaccessible via telnet,
while still passing traffic through its interfaces.
Total interfaces on unit:
(2) WIC-1DSU-T1-V2
(2) WIC-1ADSL
(1) NM-HDV2-1T1/E1 w/ (2) PVDM2-32 daughter cards
The other thing we did recently is add the NM-HDV2-1T1/E1. Before
adding these cards, we never had an issue.
Running a "show controller serial x/x/x" and a "show buffer" through
the Output Interpreter, I am told:
"WARNING: The interface Serial0/0/0 has reported 449 'overruns'.
This is because, the input rate exceeds the ability of the receiver
to handle data .... Paste the output of the show buffer command
output into the Output Interpreter to check whether the buffers can
be tuned. "
"ERROR: Since its last reload, this router has created or maintained
a relatively large number of 'h2p1 buffers' yet still has very few
free buffers. The above symptoms suggest that a buffer leak has
occurred."
I'm wondering if a buffer leak could be the source of the issue.
Maybe this wasn't a problem before the router had the new DSL cards
and T1 network module, but now the new cards are claiming too much
memory and the buffer leak is causing issues.
We could try down or upgrading the IOS ....
Thanks for advice,
Adam
