[Xymon] Monitoring sql server 2012 - Error - Length specified in network packet payload did not match number of bytes read

Hello, I am trying to implement an Sql server 2012 monitoring script. Installed the dbcheck.pl script from this link : http://sourceforge.net/projects/hobbit-perl-cl/ . While running I am getting an error.

Sql server log : "Length specified in network packet payload did not match number of bytes read; the connection has been closed. Please contact the vendor of the client library. [CLIENT: XXXXXXXXx]"

xymon log : ERROR on 192.168.1.1 : Timeout connecting to DBI:Sybase:host=192.168.1.1;port=1433;encryptPassword=1!

Can anybody please help me to resolve this error ?

Thanks Anoop
