ModbusTCP ERROR - Error finding service with type vebus at device instance 261

Dear community,
we got 80+ industrial installations (agriculture) using Victron products for stand-alone operation, manly using Venus, SmartSolar, Multiplus 1+2.

The Venus is connected to a B&R PLC via ModbusTCP. I have been using this since like 7 year +, but since releases v2.8x and 2.9x the ModbusTCP connection isn't running smoothly no more.

Every 10 -20 hours i get connection errors saying "Error finding service with type vebus at device instance 261". This is not for long and occurs randomly. But while this error persists, data delivered at id 242 is incorrect, resulting in errors within our PLC (we monitor all Multi function for animal safety - no AC from Multi -> no ventilation = crisis).

Is this known? Can this be fixed or averted somehow?
