[ns] Scheduler: Event UID not valid! without RTS/CTS

[michelenuti@alice.it]

Hi NS users,
I remove RTS/CTS from MAC 802.11 (setting RTSThresh_ 3000) and now I often (but not always)
receive this message:

Scheduler: Event UID not valid!

and the simulation stop.
Does anybody knows why and how to solve the problem?

Thanks a lot,
Michele
