[GSS](6.4.z) JBPM failed to start because of timeout issue while registering jbpmProcessInstancesWithVariables data-set due to huge data in variableinstancelog table

ISSUE: Server failed to start If the row count exceeds 60,000 in variableinstancelog table.
Data-Sets are getting registered at server start time, when I debug the log I noticed that all the data-sets are registered fine with fraction of milliseconds except the jbpmProcessInstancesWithVariables data-set. This is not registered because of huge data in variableinstancelog table.
Hence there is a time-out in loading the data-sets and finally server is not starting with time-out error.
