MySQL Forums :: JDBC and Java :: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

I'm getting error below

### Error querying database. Cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 44,454 milliseconds ago. The last packet sent successfully to the server was 44,454 milliseconds ago.
### The error may involve defaultParameterMap
### The error occurred while setting parameters
### Cause: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

The last packet successfully received from the server was 44,454 milliseconds ago. The last packet sent successfully to the server was 44,454 milliseconds ago.

I have a job that queries the database (through ibatis )every minute and on occasion will produce error above.

Environment as follows
Windows XP
Java 1.6
MySql 5.1.35
ibatis 3 beta 7

Any ideas of how to solve?

Thanks
