I was right, it was fun! Unfortunately it also caused a segfault. The segfault appears to be on socket closure when a *lot* of ractors are running at once. The attached tarball includes the code you need to make it happen. Run `bin/server` in one terminal/screen session/tmux window/whatever, and `./bug_bench.sh` with the other. You'll need to have the apache benchmark utility installed. ---Files-------------------------------- reproduce-my-segfault.tar.gz (10 KB) error_log.txt (38.6 KB) -- https://bugs.ruby-lang.org/ Unsubscribe:
