VNC Stopped Working After Installing Solaris 9 Recommended Patches

[Steve Waltner]

I'm running the free distribution of RealVNC 4.1.2. I installed the  
Solaris 9 Recommended patch bundle I downloaded on Feb 21, 2007 onto  
my Solaris 9 systems last night. This was primarily done to get the  
updates for the DST changes. Now, we're having trouble using VNC.  
Here's the arguments to my Xvnc process...

ra:~> /usr/ucb/ps auxwwwwww | grep Xvnc | grep swaltner
swaltner 22928  0.1  0.1 8152 6784 pts/27   S 11:24:45  0:00 Xvnc :14  
-desktop ra:14 (swaltner) -httpd /soft/cfr/vnc/4.1.2/java -auth /home/ 
swaltner/.Xauthority -geometry 1024x850 -depth 16 -rfbwait 30000 - 
rfbauth /home/swaltner/.vnc/passwd -rfbport 5914 -pn -IdleTimeout=0 - 
fp /usr/openwin/lib/X11/fonts/misc/,/usr/openwin/lib/X11/fonts/75dpi/
swaltner   148  0.0  0.0 1048  840 pts/27   S 11:40:04  0:00 grep Xvnc
ra:~>

When I try to send X11 graphics to that Xvnc process, I get BadAtom  
errors.

ra:~> xterm -display ra:14
Warning: Actions not found: string, scroll-back, scroll-forw
xterm:  unable to open font "8x10", trying "fixed"....
X Error of failed request:  BadAtom (invalid Atom parameter)
   Major opcode of failed request:  20 (X_GetProperty)
   Atom id in failed request:  0x0
   Serial number of failed request:  90
   Current serial number in output stream:  90
ra:~>

Out of the 157 patches in the patch bundle, each system had anywhere  
from 85-125 patches that were installed/updated, several of these  
were related to X.

The problems seem to come and go, which is the really annoying thing.  
This was working perfectly when I went home at midnight last night,  
but failed at 8:00. Many users report that trying to start the VNC  
session a couple times eventually starts a session.

I've got backup copies of my VNC server log files from before the  
upgrade, and while there are several warning/error messages in it,  
except for timestamps, they are exactly the same.

Any suggestions on where to look?
