Fix a cron file for Android game (Ruby/MySQL)

Please, please read fully before submitting your bid. I need a programmer to fix a few lines of code, potentially a very short job but if this works out I'll be happy to hire on an ongoing basis. This is for an Android game that is live in the Google playstore called GPS Tycoon. The original developer is no longer able to work on the game and yesterday when the server rebooted a cron is no longer working. It may just need to be restarted is all but there is a weakness in the code that should be fixed because the bug reappears. The code is native Android for the front end and Sinatra in the backend. Programmer should have good skills in Java/Android native, Ruby and MySQL. App uses Google Maps API so experience there is also a plus. All code is hosted on BitBucket. However, again, this first project is simply to fix the hourly cron. The problem is most likely that the cron is getting cut off at a certain point (memory issue?) or that users are getting negative game asset resource values which prevents the cron from assigning assets to that user. For THIS particular project all I am looking for is a fix to this issue. However, at the same time, I am also hoping that the coder will want to continue work as this is an ongoing project. If you would like to see the cron file before placing your bid, that's ok, just ask. When you submit your proposal please don't send me your template form with links to other projects. None of that matters to me. Just address this issue so I know you understand what this is about. I look forward to working with you!
