1) no
2) no
3) yes at all cost
4) both, exceptions are logged with context (current bindings, etc)
5) undecided, under close examination however
6) never have to restart, we check what cause the error and correct it
externally if required
most errors are reported immediately, may depend on the failed process
being critical
or not.
Up times above 250 days, restarts only required when upgrading stuff.
