Hi,
I suspect you are running into CSCsb61172, fixed in 12.2(25)EWA5.
To verify if you are hitting this with certainty, check "show platform hardware interface all"
Global Hardware Gigaport State
------------------------------
RxIpg : 6
TxIpg : 264
FreeListCount : 329 <<<-----
Note that typical values of the free list count are between 20,000 and 64,000 depending on the traffic
being switched. A count of 329 above is too low and indicates a memory leak.
HTH,
Bobby
