[systemd-devel] service stop taking too long

[Pradeepa Kumar]

sorry for not being clear earlier.
 may be i am not explaining properly.

In XYZ.service:
ExecStop: myscript1

$cat myscript1
echo "inside myscript1"


and

The sequence in jounrnalctl logs are:

 May 18 01:18:06 machine1 systemd[1]: Stopping "XYZ service"...
...
 May 18 01:18:46 machine1  myscript1[3941]: inside myscript1

As you can see, the beginning of execution of myscript1 took 40 sec.
