ME-C3750-24-TE and IOS memory problem

If you meet a IOS crash bug such as :

Pool: Processor  Free: 164996  Cause: Memory fragmentation
Alternate Pool: None  Free: 0  Cause: No Alternate pool

-Process= "HQM Stack Process", ipl= 0, pid= 112
-Traceback= 26C41C 31CB0C 3222C8 B1FDF0 B08F50 35B764 351D2C
%SYS-2-MALLOCFAIL: Memory allocation of 36688 bytes failed from 0xB1FDEC, alignment 8
Pool: Processor  Free: 164996  Cause: Memory fragmentation
Alternate Pool: None  Free: 0  Cause: No Alternate pool

-Process= "HQM Stack Process", ipl= 0, pid= 112
-Traceback= 26C41C 31CB0C 3222C8 B1FDF0 B08F50 35B764 351D2C

And your environnment is MPLS/OSPF on this kind of hardware, you can be aware of that : When you add a new OSPF neighbor to mesh your network, you can meet memory problem and crash.

For my side, a ‘no mpls ip‘ resolv my problem, before an upgrade of IOS.
