[Clas_offline] CCPR 65235 ( caldb mysql error during connection to server.)

[John T. Goetz]

I found a MySql bug thread that looks related to this problem:

http://bugs.mysql.com/bug.php?id=25479

here's another:

http://bugs.mysql.com/bug.php?id=5656

This matter rather urgent for g12 as it is holding up our pass 1.
Thank you,
Johann.
