is python crashing? (i.e. is the python process still running after its freezing?)
you could install strace via pacman
I actually quite like the web editor, the only thing i dont like is the left hand pane, where the files and save options are… I think the save options, probably should be buttons at the top, so they are always available without having to scroll thru the whole mode list.
I think when I get time I might take at look at improving the editor, as its pretty sound otherwise, and the workflow when developing modes is really fast
btw… if you do want to edit remotely, you’ll also want to look at the osc messages that is used to tell ETC/python that the file has change, and so to reload the mode… you can find this either in the web editor code, or osc.py.
(sorry cant remember the message off-hand)
btw… if your going down the route of remote editing , Id also recommend switching to using the sdcard for storing modes, see my organelle post on this… this only requires a very small change in etc_system.py, my experience is the sdcard is much more reliable than usbsticks.
(and frees up the usb ports for midi controller(s) without needing to carry around a usb hub as well )
