### Apache NetBeans version Apache NetBeans 26 ### What happened I run 5 projects that write to different tabs in the output window. One of them writes about one page every two minutes. After some time which appears to be random, CPU usage goes up from a negligible amount to to about 25%. With a system of 4 cores, this would be 100% for a single core. I tried to fix this by ending all processes in the IDE and closing all output tabs. This doesn't have an influence on CPU usage. Finally I have to re-start the IDE and start again. My Windows 10 system has 16GBytes. In Windows Task Manager, memory usage is about 1.9GBytes. There are no memory errors. I would expect that if CPU goes that high for any reason, that it goes low again with no IDE activity and no open files in the editor. But the CPU usage stays at the maximum forever. I am attaching 2 profiling snapshots and a log file. ### Language / Project Type / NetBeans Component _No response_ ### How to reproduce Unfortunately I do not have a reproducible test case. I hope that the profiler snapshots and the log file will be sufficient. ### Did this work correctly in an earlier version? No / Don't know ### Operating System Windows 10 ### JDK JDK 23 ### Apache NetBeans packaging Apache NetBeans binary zip ### Anything else [messages.log](https://github.com/user-attachments/files/21376871/messages.log) [selsamplers.zip](https://github.com/user-attachments/files/21376883/selsamplers.zip) ### Are you willing to submit a pull request?
