[cisco-voip] VNC Connection Flakey?

[Miller, Steve]

I have definitely had OS updates when the server "hung" with VNC and I
had to go physically push the power button on the server, but I don't
recall having a server hand on a simple reboot.

Recently, I discovered that Real VNC caused one of our Unity servers to
hang
on a reboot.  This meant that I could not access the server remotely
with
RDP, APC KVM or Real VNC.  It would hand right before Real VNC would
display
the prompt for the CRTL, ALT Delete so that I could enter the log in
credentials.

A quick look at the application logs pointed to Unity Cisco Security
Application preventing the Real VNC "hooks" which monitor graphical
changes
on the desktop.  Has anyone else experienced this?  I selected the
"windows
polling" option to avoid the use the "hooks" option.  The server
rebooted
without getting stuck.

...Or make sure your server isn't experiencing outages or crashes due
to running out of memory or CPU. have you checked for anything like
that?
