I excluded the default Tomcat in SpringBoot and chose Undertow as the web container. My server specification is 4 cores and 8GB. Undertow is configured as max-http-post-size: -1, buffer-size: 1024, direct-buffers: true, threads.io:8, threads.worker:1024. However, my program is prone to pseudo-death, that is, the thread is blocked, the CPU is normal, and the server memory is normal. How can I solve this problem?

Hello LCZ,
Looks like some other components in the application is creating the issue. The thread report looks normal as there are no issues reported.
But, there is one database logging compoent is used in the application. It is a good idea to check that component and its configuration.
Hello there
Start by looking through thread dumps to find blocked threads, in the XNIO worker pool; in order to troubleshoot the spring boot pseudo death brought on by undertow and XNIO thread blockage.
To enable extra threads for handling requests, increase the workerThreads option in undertow. Examine XNIO threads for blocking operations, such as lengthy database searches; transfer these jobs to a different thread pool or use async for asynchronous processing.
To prevent thread depletion, check connection pool configuration and make sure thread management is correct.
