IDM Drivers stop processing events when the log file location runs out of space

IDM Drivers will stop processing events when the log file location has no more space.  The disk drive is full.

This is working as designed and is done to prevent any IDM corruption.  Since you should only be running with tracing on when troubleshooting a problem, you would not want the engine to skip recording events.  Also, anytime a disk or drive space becomes full, a chance for unstable programs is very high.  It is recommended that you limit the size of the trace file rather than leaving it a unlimited.
