[kronolith] Free/Busy Retrieve Error

[Anant S Athavale]

  Hi list:

  I also have the same problem.  I also reported this in the list. 
But, nobody replied. I am also not a PHP expert.  I request the
experts to look into this and guide us.
Regards,

Anant Athavale,

Quoting akulick at backup.corp.eoscene.com:

Specifically,
