[c-nsp] IP_VFR-4-FRAG_TABLE_OVERFLOW

[Tony]

Hi,

Too many fragmented packets requiring reassembly before router can deal with the full packet, run out of memory to store fragmented packets, dump fragmented packet (no more memory to store in), get this error.

The fix is as you have already stated.


regards,
Tony.
