What have you tried thus far, what do you mean by "check port" ? If the port is closed how can you get the services PID? If you provide a more precise question, I can probably help you - conceptually what you are trying to do can be done with tools like "logger" for logging, netcat to check if a port is open or fuser to check the process ID associated with a port, but its hard to put these together without knowing the service, as it appears you are asking to "test for a negative", and thus you can't get some information you need from the negative result and need to look elsewhere for it.– davidgoSep 11, 2013 at 5:59

i think Port close but PID can exist because service hang.:D– GatoSep 11, 2013 at 6:38

Surely the solution would be to check if the service is working (if its TCP you could use nc (netcat), and then if its not working send a command to "killall" the process ?– davidgoSep 11, 2013 at 8:26
