VNCViewer locks

[DGPickett@aol.com]

PS: If I use another host (not where Xvnc is) to run vncviewer,  the locking 
is prevented.  There must be some signaling on localhost that  does not happen 
on Ethernet, or the timing is just slightly slower, that Solaris  does not 
need to send zero length messages that taste like EOF.  Maybe I'll  route it 
through TCP_relay and see if that makes it slow without entangling  another host 
in the reliability model.
 
Best regards,

I have a variety of  Solaris 8 boxes where I run VNC 4.1.1 with no problem, 
but now I have a  Solaris 10 box with new 1593 MHz CPUs, and when vi sets the 
visual bell off on  my xterm, vncviewer locks.  I ran a truss, and saw that 
vncviewer got a  zero return from read on the socket.  Since it is just a 
different box, I  suspect some subtle timing issue.

There is a similar open thread on  vncviewer using SSH, which might be the 
same problem.

In the past on  Solaris, I have occasionally seen sockets returning zero to a 
read()  without being at EOF (connection closed or disconnected).  We wrote a 
 loop with poll(0,0,1) to insist on 50 consecutive return zero  read() 
returns across 50 Milliseconds before declaring EOF to avoid  this!
