[OpenSIPS-Users] Help!!! Getting ERROR:nathelper:nh_timer: out of memory

[Bogdan-Andrei Iancu]

Hi Alex,

Yes, you are right - it may be the case also, but such scenarios cannot 
be prevented - they simply happen - as you said, just ignore them :). 
Probably that message should not be loged as an error, but as simply 
info or debug.

Regards,
Bogdan
