You can try and add the "copytruncate" option to your samba logrotate 
config file.
This is what i have to use on debian wheezy:
/etc/logrotate.d/samba
-----------------------------

...

/var/log/samba/log.samba {
     weekly
     missingok
     rotate 7
     copytruncate
     compress
     delaycompress
     notifempty
}
----------------------------
