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,
| #!/usr/bin/env bash | |
| # Kill an Erlang process by node name | |
| # | |
| # e.g.: kill-erlang-node kred | |
| # Check usage | |
| if [ -z "$1" ]; then | |
| echo "Usage: `basename $0` NODE_NAME" | |
| exit 1 |
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:

** exception exit: {normal,{gen_server,call,
[<0.53.0>,
{{timeout,infinity},
wait_for_version_negotiation},
