Definitely should not be happening. Since it's likely related to TurboVNC, my suggestion would be to build the TurboVNC Server from source and include debugging information in the build:
sudo apt-get install gcc make git cmake libpam0g-dev libsm-dev libice-dev libxext-dev libssl-dev git clone https://github.com/TurboVNC/turbovnc.git cd turbovnc mkdir build cd build cmake -G"Unix Makefiles" -DTVNC_BUILDNATIVE=0 -DTVNC_BUILDJAVA=0 -DCMAKE_BUILD_TYPE=RelWithDebInfo .. make Now launch the server with: ulimit -c 10000000 bin/vncserver -debug When the server crashes, it should leave a core file. Load that core file into gdb: gdb bin/Xvnc {core file} Type 'where' in gdb to print a stack trace. Create an issue in the TurboVNC GitHub tracker: https://github.com/TurboVNC/turbovnc/issues/new and post the following: -- The stack trace you obtained above -- The console output from the TurboVNC Server -- What version of the RealVNC Viewer you were using (example: 4.1.2) -- What client O/S you were using (examples: Windows 7, iOS 9, macOS Sierra) -- What RFB encoding you were using (examples: Hextile, ZRLE) All of that aside, while it is a bug for the RealVNC Viewer to crash the TurboVNC Server, and I definitely want to fix that bug, I also cannot recommend using the RealVNC Viewer. The TurboVNC Viewer will be necessary in order to achieve full performance with our server.
