And has anyone experienced the extension crashing with error

Extension respawning too quickly: C:\ProgramData\osquery\plgx_win_extension.ext.exe
Created and monitoring child (20340): C:\ProgramData\osquery\plgx_win_extension.ext.exe
Refusing to reister duplicate extension plgx_win_extension
Duplicate extension registered

Then the extension re-initializes

curious to know more on this. Anything specific that you can recall which led to this state?

Not yet, only that it happends both with osqueryd and osqueryi after running for a certain amount of time, only that osqueryd doesn't reload the extension

running osqueryd and osqueryi with config to launch the plgx extension, is not supported. as only 1 instance of the extn process can be executing at anytime and that is detected and flagged.
