Package: snmpd
Version: 5.4.3~dfsg-2
Problem:
`invoke-rc.d snmpd restart' may sometimes fail if the snmpd daemon
does not terminate by the time the init script's 2-second sleep
expires:
invoke-rc.d: initscript snmpd, action "restart" failed.
The chance of failure is significant enough at sites where
restarting snmpd across several hundred servers every day can
reliably trip it over.
Expected behaviour:
The init script should wait for the daemon to terminate before
trying to start it back up again. Adding --retry to
start-stop-daemon solved the problem for me.
