I think there is a bug with transmission-daemon in Alpine Linux when try to gracefully stop it with INT or TERM signals.

I did the following test on both Archlinux and Alpine in an interactive docker container:

* Run this commmand:

transmission-daemon -f

• Add a torrent file with RPC client.
• Send INT signal (Ctrl + C) or send a TERM signal with kill.

On Archlinux: the signal was intercepted, and transmission gracefully exit (save .resume files, write a message “Closed session” in logs etc.

On Alpine: sometimes the signal was simply ignored (I can doing 100 Ctrl + C, it does nothing), sometimes I have a segmentation fault.

Notes :

• The same test without adding a torrent works perfectly on both Arch and Alpine.
• There are exactly the same version of transmission in Archlinux and Alpine (2.92).
• I have try to compile transmission myself, but it does not change nothing.

I have no idea why.
