 yes.

 SYN, but no reply. client then falls back to nd and thats bizarre, but =
 what happened.
 
 multiple times btw.

 yes.

 tcp6       0      0 *.873                  *.*                    LISTEN
 
 not in a FIN_WAIT_2 or TIMEOUT or anything.
 
 pstree showed no process in zombie.
 
 > 5) you added what exactly to inetd.conf?
 
 rsync   stream  tcp6    nowait  root   /usr/local/bin/rsync rsyncd =
 --daemon -6
 
 Look, My gut feel is that this was a one-off.=20
 
 If you get other people saying hmm.. some net trash is left active in =
 the kernel in V6 sometimes then this might be useful debug of when it =
 was seen in a kernel, but at this point it cleared across reboot, and I =
 have no further debug I can give. I can't reproduce.
 
 mark it stalled or close?
