Github user JonZeolla commented on the issue: https://github.com/apache/metron-bro-plugin-kafka/pull/20 I wish I had more time to work on this, but it may be a while before I could revisit. What I found was that if any of the `delete`s are duplicated it segfaults on exit. From some commit messages it seems that in bro, the destructor is called from the main thread, but `DoFinish` is called from a child thread, so we should keep this cleanup in `DoFinish`.
