[Bug]: org.apache.plc4x.java.api.exceptions.PlcProtocolException: Server returned error BadTooManySessions (0x80560000)

[ShawnKion]

What happened?

When I tried to read some nodes multiple times, the issue of too many sessions occurred.
I'm wondering if there is a configuration file that I can set some values to limit the max session I need?

Hello @ShawnKion,
Can you share some more information - how do you scrap PLC, how long it does take to get this error, and how many threads you use in your application?

Strictly speaking it is runtime issue, so we have to look closer at how you read data and, probably, what are server settings.
