Did you find any workaround?

Possibly related to issue in sshpass itself here:

Googling around I've noticed other apps that use sshpass having the same
issue like the following:

ansible/ansible#5007 ansible/ansible#5007

-- System crash report (happens almost every time I use "mup logs")

BTW: Is this only happens for "mup logs", does it work for others?

Hey @arunoda I didn't find a workaround when using "ssh-pass", but when not using it, and instead relying on "pem" file it works without any problems since it bypasses ssh-pass. It happens on all remote actions using ssh-pass (from what I saw).

[arunoda]

Yeah. ssh-pass is an issue. I will try to migrate into ssh2: 100% node ssh
module. After that this would get fixed.

Awesome

Not sure how Arunoda terminates sshpass during its execution but if it's via the SIGINT signal then I have a fix for sshpass. There seems to be some race condition when sshpass is abruptly killed via ctrl-c or SIGKILL/SIGTERM it causes a kernel panic in MacOS. Pretty crappy that a userspace application could trigger that in a kernel.. Anyhow I have a patch for sshpass if you're willing to re-compile from source:

@th48ad ssh keeps crashing my Air and so I googled here.
I tried your patch, now it sleeps 5s after ^C. However the crashes still happened
