Hi there,

after running somewhat stable for a couple of days (since we started
using 1.9.18p4) tommorow morning nearly all our samba servers in
different subnets doing the remote browse sync thing together were some
kind of unresponsive: 

What I have seen with tcpdump was PCs broadcasting for their server
names but no answers from the servers.

Only one nmbd was running on those machines (we run them as daemons) an
in their log file we found soemthing like

   Got SIGPIPE
   error connecting to 160.19.1.1:139 (Broken pipe)
   sync_browse_lists: Failed to start browse sync with XXXBA001

After stopping that still living nmbd and restarting it everything was
fine again.

It is perfectly possible that the link between subnet 160.18 and 160.19
was broken at this moment caused by a leased line maintenance done by
our line provider.

What still irritates me that we lost responsiveness of nmbd: a later
test showed that the nmbd process son is stable against SIGPIPE: the
father just goes on and starts another son.

The relevant parts of our smb.conf:

  
[global]                                                               
        
      workgroup = XXX.DOM
      remote announce = xxxdg001 xxxdg002 xxxba001 xxxba002
      remote browse sync = xxxdg001 xxxdg002 xxxba001 xxxxba002
      domain master = yes
      local master = yes
      preferred master = yes
      os level = 35
      name resolve order = host
      wins support = yes
      wins proxy = yes

Has anyone had this situation?  Is there a cure?

Regards,
        Robert
