When starting a SFTP channel towards a system where user does not have a shell (i.e. it has /bin/false or equilvalent assigned in the /etc/passwd a misleading error message is returned to the user:
1> test:go().

[<0.53.0>,
{{timeout,infinity},
wait_for_version_negotiation},
Example of OTP deadlock via the application controller.
In OTP, the application environment is handled via a ETS table, which
is accessed via the application_controller process. Whilst reading
an environment variable is implemented as a mere lookup operation,
writes are serialized through the application controller.
In other words, it is not possible to set an environment variable
from a terminate/1 callback in a gen_server which traps exits,
