I had the same problem. I suspected some sort of racing condition. It can also happen with Server or Web-Server crash.

I am taking a similar approach, but with two files in place of one. If main counter file is blank, use values from counter.bak file. 


Lock Counter_File

  Read Count 

    On Fail 

      Read Counter_File.bak

  Increment

  Write Data to Counter_File

  Copy Counter_File to .bak file.

Release Lock
