   Hi,
   this is not a bug in Lucene, it can be two possible problems:
   - You are closing IndexReaders while queries are still running. Due to 
limitations of unmapping memory mapped files in Java 11 (no thread safe 
unmapping), this may cause SIGSEGV or SIGBUS. This is well known. To prevent 
this consider upgrading to Lucene 9.4 and Java 19 with preview options enabled.
   - The code looks like it tries to access Netty files, so it looks like not 
related to Lucene.
   
   To me this looks like a mixture of using netty and possibly also closing 
index files while there's still access from other threads.
