Hi,

I keep getting the error reading value from point from the MangoES3.7 and no ideas what's wrong wth the polling. after I pull out the ma.log and found that seems like some deleted points data still appear on the SQL database.

The he GC-RP11 is a BACnet/IP Router which only a single Modbus RTU to BACnet MS/TP controller which polling 90 over points. increase MangoES datasource pollng interval still not improving the communication.

Appreciated if there are any help or advice.[(https://drive.google.com/file/d/14dwGtATJgCwIGz4nEL4K8xoOwpnHuBDs/view?usp=sharing)](link url)
