Jonathan, Carlos, Dave:
I've posted details in the FRS. I was able to see a segfault on one of the dmtviewers during testing this morning.
History:
Tue 3rd Sep 2019: maintenance, nuc5 upgraded from deb8 to deb9 (Carlos), launch.sh script modified to auto start dmtviewer and diaggui (Dave)
Tue 3rd Sep 2019: evening, Ed sees the FOM_STS dmtviewer crash.
Thu 5th Sep 2019: early hours, Travis sees the FOM_3-30Hz crash twice within hours
Thur 5th Sep 2019: Dave sees FOM_STS crash (segfault reported)
Carlos has been testing a dmtviewer (IFO range) on a new Nuc machine running a clean deb9 install in his office with no problems.
So, PLAN A is to upgrade nuc5 from its current old hardware with an upgraded deb9 to a new nuc with a clean deb9 install.
In the mean time, if a dmtviewer crashes, the easy way to restart it without having to reboot nuc5:
Get remote access to nuc5
xvncviewer nuc5
Open a terminal on the Desktop, and type
pkill dmtviewer
pkill diaggui
/home/controls/startup/launch.sh
