Comment(by strings28):

 I would *LOVE* to know why the writing is happening more than once.  Since
 implementing this lock file method it has stopped getting corrupted.

 I have searched Google, Bing and the WordPress forums and found no real
 solid information as to why this would be happening and the server logs
 did not reveal anything and no PHP errors were reported to have caused
 this.  There were several WordPress installations on our server and I
 modified the insert_with_marker function to put a customer marker string
 in for each installation to make sure there wasn't a strange situation
 where multiple installations were setup incorrectly (and that doesn't
 appear to be the case).

 I also checked the WordPress 'cron' jobs and none of those were doing
 anything that would be related to this problem.  If anyone has any
 debugging ideas I would LOVE to hear them and attempt to figure out what
 is going on.  Are there functions I should add logging code to to help
 find this?  I'm willing to go the extra mile here, but I'm at a loss where
 to start.
