Looks like there's a line in "stop" section that kills the script |
| 10 |
itself. Try looking for a lines like these: |
| 11 |
|
| 12 |
pkill MailScanner |
| 13 |
killall MailScanner |
| 14 |
start-stop-daemon --stop --name MailScanner |
| 15 |
|
| 16 |
Sure, they might be killing the app as well (if the process has |
| 17 |
MailScanner in it's name), but there should be full path or pid-based |
| 18 |
line instead, so the initscript will exit cleanly. |

Following command should "wipe" initscript memory: |
| 26 |
|
| 27 |
/etc/init.d/MailScanner zap |
| 28 |
|
| 29 |
...so it'll think MailScanner wasn't even started, but that should be |
| 30 |
used as a workaround rather than a solution since it leaves init-system |
| 31 |
in different state than it thinks it is. |
| 32 |
Direct effect is that it won't execute "stop" action on shutdown since |
| 33 |
it won't know the script even started. |

Could be because of aforementioned script "self-destruction". |
| 45 |
If sendmail really started by the same script, not as a dependency, |
| 46 |
that is. |

Try using "start-stop-daemon -m/-p/--exec" to start and stop binaries, |
| 58 |
instead of relying on process names (which can be easily changed, btw) |
| 59 |
and try to use app-created pidfiles, if the launched app has this |
| 60 |
capability, since it should know better which of it's processes should |
| 61 |
receive stop signal. |
