We are getting the attached Modbus error on start up of gateway. Once gateway is up and running we aren’t seeing errors like this after that and Modbus devices appear to be running as expected. Logs attached. Running 7.6 rc5 [logs.bin.gz](https://us1.discourse-cdn.com/inductiveautomation/original/2X/f/f60232969dc1f00be6220e1dd54ecb7c9dd3c232.gz) (533 KB) ![](https://us1.discourse-cdn.com/inductiveautomation/original/2X/d/dfd577d3c7498e447cd6a0e7a42a3322137c0f0f.PNG) ---

Thanks. This one is harmless, but I should figure out how to squelch that annoying and scary error message it generates. ---

Thanks for the info Kevin. It looked like it might be harmless since the system appeared to be working correctly after boot but wanted to verify.
