Dear Mr. Carpenter,

Thank you kindly for your help and these nice suggestions.  Thank you
for CCing Mr. Finger.  Actually, I stumbled across his name in my online
searches as on of the developers of this driver, and that's why I tried
to seek help here.

I was able to repeat the problem and then capture /var/log/messages.  It
is attached to this email.  hopefully it went through?  It's hard for me
to help locate the problem, but I believe I initiated the vnc over ssh
action around line 2892-2910 of the attached
("201504220906-0700-messages.txt"), with corresponding messages
2892-2910 being:

Unfortunately, that log segment does not have help for the problem. In fact, the logs seldom have any useful information. When a critical error occurs, the results are sent to an in-memory buffer and may be sent to the disk, but they write is not usually completed. When the system is restarted, the info does not make it to the logging file.

At the moment, I am running x11vnc server over an ssh link with vnxviewer displaying the image. Other than the slowness of the network link, I am having no problems - the v4.1.8_2499 branch is what is running.

Next, I will try the master branch.
