No named was running.  I shall look through the other logfiles
and see if anything more arises.

If you didn't write too much to your /var/log partition since the
file was deleted, you can still try to recover the log files using
strings and grep - for instance like this:

 strings /dev/raw-device-of-var-log | egrep '(Jan|Feb|Mar)  ' | sort -u
