I have a mac mini os x 10.6.4 which I use to host a web app for private use only. For certain functionality I needed a cron job so i used lingon (http://lingon.sourceforge.net/) to setup a launchd cron job - this creates a plist file in the following folder /library/launchDeamons folder. the job it self is just "curl -s localhost/api?method=cron" and this works when executed from the terminal. it executes every 5 minutes just fine but after 2 days it just stops when i restart the machine if works again for 2 days and then stops again. any ideas what could cause this strange behaviour, or where i could look to find the error?
