getting this warning on deleteAllRecords();

2012-01-24 14:05:54,494 WARN [pool-3-thread-1] com.servoy.j2db.util.Debug - Could not connect next foundset chunk, re-loading entire PK set

I think this is because my dataset result is > 200. Can anyone help me on how can i correct this?

function deleteOrganizationData(orgIDList) {
	var serverTables = databaseManager.getTableNames(globals.DB_SERVER_NAME);
	for (var index = 0; index < serverTables.length; index++) {
		var tblFoundset = databaseManager.getFoundSet(globals.DB_SERVER_NAME,serverTables[index]);	
		var orgIndex = tblFoundset.alldataproviders.indexOf("username");
		if (orgIndex != -1) {
			var tablePk = databaseManager.getTable(tblFoundset).getRowIdentifierColumnNames()[0]
			var sql = "SELECT " + tablePk + " FROM " +  serverTables[index] + " WHERE username IN (?)";
			var ds = globals.cmn_executeQuery(sql,["ABC"],-1);
			if (ds.getMaxRowIndex() > 0) {
				tblFoundset.loadRecords(ds);
				tblFoundset.deleteAllRecords();
			}
		}
	}
}
