Thought I would just send an update on this. Thanks for the all the suggestions.
To get around our particular issue I just added some retry logic to the /etc/init.d/ script. When it runs it if finds that the operation has failed it pauses for a second and will try again. It will try up to three times before giving up. Running more tests we were able to see that on some occasions it still fails on the first attempt but so far has always been successful on the 2nd.
