[ns] ns2 Segmentation fault - queuing

[F A]

Hi all
Does anybody know why most of queuing mechanisms implemented in ns2 (like:
sfq, drr, srr, and the rest except DropTail and PriQueue), when it is used
in multihop wireless network, it generates Segmentation Fault error,
especially when the simulation time increases, but when they are used in
wired network topology they work fine.
