and proper distributions ship logrotate configs by default

copytruncate
Truncate the original log file in place after creating a copy, instead
of moving the old log file and optionally creating a new one. It can be
used when some program cannot be told to close its logfile and thus
might continue writing (appending) to the previous log file forever.
Note that there is a very small time slice between copying the file and
truncating it, so some logging data might be lost. When this option is
used, the create option will have no effect, as the old log file stays
in place.

[root at srv-rhsoft:~]$ cat /etc/logrotate.d/samba
/var/log/samba/* {
    notifempty
    olddir /var/log/samba/old
    missingok
    sharedscripts
    copytruncate
}
