[c-nsp] Where did the memory go ? SYS-2-MALLOCFAIL

[Bas]

Hi all,

I've looked around but cant find an explanation.

-------------
R1#sh diags 4 | i SLOT|Mem
SLOT 4  (RP/LC 4 ): 4 Port ISE Gigabit Ethernet
        Processor Memory: MEM-LC-ISE-256=
        Packet Memory: MEM-LC1-PKT-512=(Non-Replaceable)
  Processor Memory size: 268435456 bytes
  TX Packet Memory size: 268435456 bytes, Packet Memory pagesize: 16384 bytes
  RX Packet Memory size: 268435456 bytes, Packet Memory pagesize: 16384 bytes
-------------

Then

-------------
SBP-R1#execute-on slot 4 sh mem free | e 00000
========= Line Card (Slot 4) =========

               Head     Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
Processor   443A0AC0   174454080   152480916    21973164    21969144    21926716
-------------

268435456 - 174454080 = 93981376

Where are those ~90MBs of memory?
With my SIP600 I do not see a difference in total memory.

Reason I ask is that I tried to configure multipath EBGP with one of
our transit carriers
Once the second full table was loaded all 4GE linecards stopped forwarding.

from the log:

--------
Feb 24 13:30:01.544 CET: %FIB-2-FIBDISABLE: Fatal error, slot 4: no memory
Feb 24 13:30:01.644 CET: %FIB-2-FIBDISABLE: Fatal error, slot 1: no memory

Feb 24 13:30:01.812 CET: %FIB-2-FIBDISABLE: Fatal error, slot 3: no memory
--------

and

-----

-----

So, not enough memory on the 4GE LC's
The box has 6 full tables,

Can anyone help me resolve this?

Thanks in advance,
