Root Cause

From the Systemout logs below details has been observed .
[8/8/16 1:32:42:197 EDT] 00000017 DSConfigurati W   DSRA8200W: DataSource Configuration: DSRA8020E: Warning: The property 'portNumber' does not exist on the DataSource class com.teradata.jdbc.TeraConnectionPoolDataSource.

Users  database team announced that they were “implementing a gateway Efix on Teradata appliance for monitoring and  with this “client Teradata JDBC versions should be at least 14.00.00.12 version”  and they are using  version 13. With the old drivers, it was causing a thread dump and all connection pools stopped working.
