rtcd.log can become gigabyte large

[130s]

I don't know if this is Hiro/NXO question. I don't know either the condition when this can happen. But I got from a user a single rtcd.log file that is 1.4G. It's content is mostly lines like below. Too large log files like this are difficult to handle in any way. Is there a way to set the maximum size of a single log file?:

position limit over RARM_JOINT2(5), qRef=-2.80412, llimit =-2.75762, ulimit =0, servo_state = ON, prev_angle =
 -2.80412
position limit over LARM_JOINT2(11), qRef=-2.79798, llimit =-2.75762, ulimit =0, servo_state = ON, prev_angle 
= -2.79798
