This is not a swapping problem! You have to have two nmbd processes running with 
1.9.18p8. The one getting swapped out is just the one doing async DNS lookups, it 
is not the one responsible for a disappearing server.

What really happened is as follows: The "father" nmbd died for some reason (nmbd 
is somewhat unstable in 1.9.18p8, especially when using "remote" keywords). The 
son process (still living) is no longer active (the father - being dead - is no 
longer asking him to do DNS lookups) and thus gets swapped out at the next 

Look out for the number of running nmbd processes: If there are two, you will find 
your server in network neighborhood. If there is only one, it will disappear from 
the 'hood.

Does anyone know if nmbd is more stable in p10?
