VNC session dropping

Hey guys, hey aka! Happy holidays!

I have a strange problem with 5.4.66 (that was happening with 5.4.62 too!). The VNC sessions ends abruptly and a blue screen appears with the message - "I'm tired"

If the user press ENTER, or hit OK, the session reconnects with no problem. This is happening every 20 minutes, more or less. I attached the logs of the WTware client.

Thanks!

here are the logs after some drops.

Just trying to help here, but it seems that whenever there's too much mouse usage, or some "effects" on screen, like a website with some sort of flash animation, this happens.

thanks aka.

1. It's 5.4.66 version. Not 5.4.67 from my link.
2. It's another error. Not related to previous log.

Which VNC server you use? Name, version, host OS, configuration if something changed.

Hi aka, sorry about my mistakes. I attached the logs with the error running 5.4.67.

The scenario didnt change, here's what I have configured here - Centos 7 server with TigerVNC (https://www.digitalocean.com/community/ ... n-centos-7).

Do you think it could be my Linux VNC setup the problem?

Aka, I think my setup was indeed the failure point.

Turns out, if I load a VNC session with "depth 16" the problem does not happens! it only happens when I work with 32 bits sessions.

So, I configured the server to load 16 bits sessions, and edited config.txt to set framebuffer_depth=16.

When I did this, the problem stoped. I still wanna do some more tests, and will post here the results.

As always, thanks for the help aka!

I installed tigervncserver_1.7.0-1ubuntu1_i386.deb on my Ubuntu, connected in 32-bit color and run youtube in chromium for an hour. No errors :( Please, try to find exactly, which "effect" brokes session.
All errors in logs are different. Data stream broke before wtware detect error. It looks like wtware problem, but I should reproduce it to fix.
