stale pid for watchdog service

[Arijit Banerjee]

The init script for the watchdog service does not seem to remove the pid file corresponding to the watchdog and wd_keepalive daemons while stopping them using start-stop-daemon. This causes us to potentially send SIGTERM and SIGKILL to wrong processes.

This behaviour was observed on Ubuntu 14.04 and this logic appears to be present even on the latest versions of the watchdog package (watchdog_5.15-2).

Not deleting the pid file appears to be incorrect behaviour in init scripts. Is this a known issue?

Dear Arijit,
Many thanks for reporting this issue and providing a fix. I have applied your patch to the GIT repository on Sourceforge but I don't know how long it will take (if ever) to get included in the version distributed with 14.04
Regards, Paul
