### What happened? ### Isseu When executing a read request every second in an ethernal loop After 1 hour and 15 minutes the connection is not funktioning anymore when executing a read request every second in an ethernal loop. `readRequest.execute().get()` When adding a timeout off 1000 ms to the get statement a exception is thrown. After this the connection has to be terminated and restarted in order to contineu reading data from the OPC UA Server. `2024-01-18 16:35:30,658 ERROR [org.apa.plc.jav.opc.pro.OpcuaSubscriptionHandle] (pool-10-thread-1) Timeout while waiting for subscription response: java.util.concurrent.TimeoutException at org.apache.plc4x.java.spi.netty.NettyHashTimerTimeoutManager.lambda$0(NettyHashTimerTimeoutManager.java:54) at io.netty.util.HashedWheelTimer$HashedWheelTimeout.run(HashedWheelTimer.java:715) at io.netty.util.concurrent.ImmediateExecutor.execute(ImmediateExecutor.java:34) at io.netty.util.HashedWheelTimer$HashedWheelTimeout.expire(HashedWheelTimer.java:703) at io.netty.util.HashedWheelTimer$HashedWheelBucket.expireTimeouts(HashedWheelTimer.java:790) at io.netty.util.HashedWheelTimer$Worker.run(HashedWheelTimer.java:503) at java.base/java.lang.Thread.run(Thread.java:840)` This also happens after 1 hour and 15 minutes when trying to retrieve data with a subscription. ### Tested OPC UA Servers Siemens S7-1500 Lokale OPC UA Server running on the same PC ### Version v0.11.0 ### Programming Languages - [X] plc4j - [ ] plc4go - [ ] plc4c - [ ] plc4net ### Protocols - [ ] AB-Ethernet - [ ] ADS /AMS - [ ] BACnet/IP - [ ] CANopen - [ ] DeltaV - [ ] DF1 - [ ] EtherNet/IP - [ ] Firmata - [ ] KNXnet/IP - [ ] Modbus - [X] OPC-UA - [ ] S7 -- This is an automated message from the Apache Git Service.
