andygrove opened a new issue, #576: URL: https://github.com/apache/datafusion-comet/issues/576
### Describe the bug _Note: This was originally reported as an issue with xxhash64 in https://github.com/apache/datafusion-comet/issues/517 but xxhash64 is not really involved._ When running TPC-H q8 with xxhash64 enabled, the executor becomes unresponsive, with most cores at 100%. Running a `kill -QUIT` command against the process dumps the current JVM stacks and shows a 500+ line stack performing plan transformation that appears to be the issue. See attached log.
