WARN  2013-01-11 09:36:46,754 (com.serotonin.m2m2.rt.dataSource.PollingDataSource.scheduleTimeout:63) - Kitchen: poll at 2013/01/11 09:36:46 abor
ted because a previous poll started at 2013/01/11 09:36:31 is still running

      I have tried changing the timeout but that does not help at all. Does anyone know why this is happening? I have taken a look at http://mango.serotoninsoftware.com/forum/posts/list/532.page but it doesnt seem to provide a proper solution.

        You're not setting a point value in the remote device at this time. You are running a forced read:

                at com.serotonin.modbus4j.ModbusMaster.getValue(ModbusMaster.java:115)  
        at com.serotonin.m2m2.modbus.rt.ModbusDataSourceRT.forcePointRead(ModbusDataSourceRT.java:332)  
        at com.serotonin.m2m2.rt.RuntimeManager.forcePointRead(RuntimeManager.java:468)  
        at com.serotonin.m2m2.web.dwr.BaseDwr.forcePointRead(BaseDwr.java:220)

        In any case, if the data source is able to read the value during regular reads, then it would be interesting to see an i/o trace (successful vs unsuccessful).

        Best regards,
        Matthew
