Disabling ZRLE has gotten me up and running. Thanks.

Disable ZRLE encoding in the vncviewer options dialog.

There is a problem with ZRLE that I've been working on, but do
not yet have a solution. 

I've seen problems with ZRLE that can cause the HPUX vncviewer
and/or Xvnc to abort. 

For those that might be curious, the stack trace from Xvnc is:

#0  0x24468 in $$dyncall_external+0 ()
#1  0xc441c in rdr::ZlibOutStream::overrun+0x75c ()
#2  0xbdbd4 in zrleEncodeTile8+0xe94 ()
#3  0xbccc8 in zrleEncode8+0x16c ()
#4  0xc25f8 in rfbSendRectEncodingZRLE+0x114 ()
#5  0xac4e0 in rfbSendFramebufferUpdate+0x744 ()
#6  0xa9cf4 in rfbDeferredUpdateCallback+0x14 ()
#7  0x56668 in DoTimer+0x28 ()
#8  0x56330 in WaitForSomething+0x6cc ()
#9  0x2b3ac in Dispatch+0xc4 ()
#10 0x25ebc in main+0x304 () 

Any suggestions on debugging this are welcomed.
