validation query did fail to execute

Hello ,

I am upgrading from servoy 5.1.14 to servoy 6.1.5 , connecting servoy with Mysql Database with query validation select 1.
and i am getting this error in my server log

]validation query did fail to execute, connection will be killed .

I am not able to understand why , any help is appreciated .Thanks

I am getting the same type of error:

2013-06-05 17:12 RMI TCP Connection(3082)-64.89.79.443 { IP Fictitious for privacy) WARN com.servoy.j2db.util.Debug validation query did fail to execute, connection will be killed.

After Googling a lot, I come up empty handed for a possible solution.

Does anyone have any idea what this is about?

And, just to report these as I am stumped on them also, can anyone give an answer why these would appear frequently in the log:

2013-06-05 14:22 RMI TCP Connection(2665)-64.89.79.443 WARN com.servoy.j2db.util.Debug Got -1, compressing socket is closed

2013-06-05 14:54 RMI TCP Connection(2748)-64.89.79.443 WARN com.servoy.j2db.util.Debug validation query did fail to execute, connection will be killed.

Thanks so much for any help!
