Well, I mentioned that the output of "smbd --version" is "4.2.14-Debian". Is
this the package version? In Samba's source code there are mentions of 
"housekeeping" activity: in the file process.c one can search for 
SMBD_HOUSEKEEPING_INTERVAL and 'housekeeping_fn' which among other things
performs some operations with log files. Can this be the explanation?
