I'm not familiar with that error message, but a licensing error should not prevent the sensor from processing events, only signature updates.

Was this sensor working correctly and then stopped? Is this a new sensor?

I usualy forget to assign an interface to virtualsensor0 (vs0) that can cause this problem.

Sensor was working correctly till last week.

all interfaces have assigned virtual sensor.

Is your sensor in promiscious or in line mode? If it's promiscious, are you getting traffic? (show interface) and is the virtual sensor getting traffic? (show stat analysis)

Have you installed any upgrades or new sig packs around the time this problem started?

I hope you've tried rebooting the sensor.

it is in promiscious mode.

IDS is seeing traffic, have tried rebooting no effect.

I did install new sig updates, but that shouldn't cause any issues.

Signature updates sometime hide engine updates and certainly have taken out our sensors in the past. Assuming that isn't the case here (I think the 4240's have been more stable than most models), you can try to reimage your sensor software from the restore partition.
