[c-nsp] Wierd memory issue with SXI/SXI1 on 6500 w/ SUP720-3BXL

[Chris Phillips]

Every six weeks or so I am running out of memory on a 6509 w/ dual 
SUP720-3BXL with mostly 6700-series line cards.

I have 21 other nodes with this exact same configuration, some even 
running SXI or SXI1 that do not have this issue, which first led me to 
believe that the issue might be hardware related.

During our last maintenance window to alleviate the memory issue, I 
forced the standby SUP to become the active SUP.  The memory issue 
persisted, leading me back to thinking it is a software issue.

I did not have this issue with SXH* on this same device, but SXH is *SO* 
buggy, rolling back is not an option.  This leads me to believe that it 
is most likely a software issue.

The router is heavily used with 250+ BGP sessions, OSPF, MPLS, v4/v6, 
etc, but I don't think it should be consuming and not releasing 4 mbytes 
of memory each day.

Has anyone else seen this?  Anyone know a workaround?

I'm upgrading to SXI2 tomight in hopes that it resolves my issue.
