Buffer failures on boot

Greetings,

   I have a 2851 and a 1841 both serving as hub routers in a GRE multipoint configuration.  They are both receiving buffer misses and failures on startup.  I will post the output of show buffers below:

LAB-HUB-RTR#show buffers

Buffer elements:

     607 in free list (500 max allowed)

     9071 hits, 0 misses, 618 created

Public buffer pools:

Small buffers, 104 bytes (total 71, permanent 50, peak 71 @ 00:11:33):

     68 in free list (20 min, 150 max allowed)

     7083 hits, 74 misses, 0 trims, 21 created

     55 failures (0 no memory)

Middle buffers, 600 bytes (total 39, permanent 25, peak 39 @ 00:11:25):

     37 in free list (10 min, 150 max allowed)

     2233 hits, 42 misses, 0 trims, 14 created

     32 failures (0 no memory)

Big buffers, 1536 bytes (total 50, permanent 50):

     50 in free list (5 min, 150 max allowed)

     118 hits, 0 misses, 0 trims, 0 created

     0 failures (0 no memory)

VeryBig buffers, 4520 bytes (total 10, permanent 10):

     10 in free list (0 min, 100 max allowed)

     0 hits, 0 misses, 0 trims, 0 created

     0 failures (0 no memory)

Large buffers, 5024 bytes (total 0, permanent 0):

     0 in free list (0 min, 10 max allowed)

     0 hits, 0 misses, 0 trims, 0 created

     0 failures (0 no memory)

Huge buffers, 18024 bytes (total 0, permanent 0):

     0 in free list (0 min, 4 max allowed)

     0 hits, 0 misses, 0 trims, 0 created

     0 failures (0 no memory)

I have tried increasing the small/medium buffers initial size and permanent size, however there is no change.  The buffer failures for small and medium buffers are always around this many every boot.

I have also changed the IOS versions between 12.4.24(T4) to 15.1 with no luck in stopping the failures.

Thank You for any information you can provide.

Just to add to this I have also wiped the config and started with all defaults and still getting buffer failures on boot.

Any further suggestions?

Thank You
