In the L setting there is no error during the remoteshoot command, but the 240 crashes with the play command.
So in summary in record mode I can do as many remoteshoot as I want but with error messages in setting M. the 240hs crashes as soon as I do the command play after remoteshoot

This sounds like a known problem that happens on a lot of cameras. The camera crashes when you switch to play if the image file is missing. Try including -jpgdummy in the the remoteshoot command. This creates an empty file with the same name as the image. You can delete the empty files after you switch to play.

The problem in M2 size is still a bug, which I haven't seen on other cameras.

Hello

Here after ordering my trials

in M position

In L Position

con> connect
connected: Canon IXUS 240 HS, max packet size 512
con> rec
con 1> remoteshoot -quick -jpgdummy
con 4> play
con 5> rec
con 6> remoteshoot -quick -jpgdummy
con 9> play
con 10> rec
con 11> remoteshoot -quick -jpgdummy

In both cases there is no 240hs crash with the play command.
In position M there are always error messages but without blogging

In M, do you get a usable image file?

Yes it is perfectly usable. There is just the presence of error messages. There is no longer any blockage with the jpgdummy option in the remoteshoot.
As I do a photobooth the definition M is more than enough.

Thanks. Can you do a test like this
size M
one shot with rs -jpg -jpgdummy
another shot, without changing the scene or anything using shoot -dl
Upload both files. Use google drive or dropbox if they are too big for the forum.
