*Do you have listener /Oracle Net Server side sqlnet trace enabled ?
*Do you have 10257 trace set in the database?
*Do you have "immediate trace name listener_registration level"  set?

These 3 above will make LREG-related traces to be written to the trace.

--REF: Oracle Net 12c: Instance Registration (LREG Background Process) (Doc ID 1592184.1) To

LREG registers instance information with the listener. It is a critical background process for each database instance.. (if killed or Oracle goes down).

So, if I was unhappy with the size of that trace, I would still not delete it, but I would empty it by using something like -> /dev/null > lreg_trace_name.trc
