GLINT:Troubleshooting

A tmux has died

Remake the tmux, like this for glintpg_ctrl:

tmux new -s glintpg_ctrl

and then restart the thing:

conda activate pycapture
ipython
> from camstack.cams.flycapturecam import Chameleon3

... and continue like the initial alignment steps here.

Error in glintpg_ctrl tmux: CRITICAL:root:take_tmux_pane contains no live PID

Ipython is polling for the status of the hidden framegrabbers. This error informs you that one of them has crashed, therefore "no live PID" is running there and doing acquisition. The shortest route to restarting the framegrabber is to kill the python terminal in glintpg_ctrl, viz,

tmux kill-session -t glintpg_ctrl

and start it over. This will fully cycle the acquisition processes. Viz,

bmc tmux says DM going to sleep...

Just kill the bmc tmux and restart it:

tmux kill-session -t bmc

In the tmux,

hwint-bmc111 -g

etc.

Brute force

If something is broken, the brute-force approach is to restart the entire stack. This takes a couple of minutes to complete but should fix most things. Connect to scexao5 and do

cam-glintstart
