you have reminded me that I was going to try to improve the LSDC server service so that it will try to restart in case it dies, and is able to restart if there isn't a chronic issue. I'll handle that in a separate issue - will have to be through ansible |

the PV name should be refactored somewhere, such as the config_params module. if this 2024-2-nyx branch is planned to be merged with AMX/FMX, then discussions should be had about the PV name to be used for those beamlines

for now I have given it the same naming treatment as beamSize_pv above, if there is no PV in place then the feature will not be functional

is there any reason you couldn't have this in a separate thread or something? it seems unnecessarily tied to a particular function, and while this is unlikely, the checking interval for the process_immediate_functions() could be set in such a way that the popup would always trigger.

I only did it to minimize the creation of new threads, but if you think that is a non-issue then I can split it out.

This is a utility for notifying the user of server failures. After 10 seconds of the client not finding a server, it will send a popup through the popup pv.
