No available memory on a 3750

Hi,

I'm getting the message

%SYS-2-MALLOCFAIL: Memory allocation of 260 bytes failed from 0x32474C, alignment 0
Pool: I/O  Free: 2588  Cause: Memory fragmentation
Alternate Pool: None  Free: 0  Cause: No Alternate pool

-Process= "DTP Protocol", ipl= 0, pid= 145

Examining the buffers pool, it appears a lot of buffers form this addresses 236.0.0.11 and 0.0.0.11

source: 236.0.0.11, destination: 190.192.1.0, id: 0x3C80, ttl: 48, prot: 72

source: 0.0.0.11, destination: 188.192.15.0, id: 0x3C80, ttl: 147, prot: 76

How can I block this and see in what interface this info comes... Because this IP addresses are very strange...

Thanks.

That's a reserved IANA multicast address and the other address is IANA as well, you could have a bug there with a memory leak , if you reload and your still getting these alerts then you should upgrade the IOS but ui would take look at the doc below first

This link should help you identify further

I'm reading the link and I'm going to make an upgrade because the version that I have is very old, see if it helps.

I will post the results.

Thanks.
