[Samba] samba stops when cups is giving up

[Peer-Joachim Koch]

Hi,

we are running cups as print service on a single server. This server is 
also running
samba to export the printer for the windows world.
However sometimes we get the following messages on the samba file server.
At this time the cupsd is still running, but not accessible. So looking 
at the status of the cupsd
is not helpful.

Two questions:
    Whats going on with the cupsd ?
    Why is samba stopping completely(!!) working, when the print server 
is not available ?
     How can we avoid this ?

ANY help is welcome...

Thanks and bye,
    Peer
