Subj : src/sbbs3/ratelimit.hpp To : Git commit to main/sbbs/master From : Rob Swindell (on Windows 11) Date : Tue Apr 07 2026 20:00:11 https://gitlab.synchro.net/main/sbbs/-/commit/e57ac918b88b43e39f7baa9b Modified Files: src/sbbs3/ratelimit.hpp Log Message: Mutex-protect the map (the client IP/count dataset) Although this has been running for months without issue on multiple servers for vert/www/git.synchro.net, I did observe *a* (one) crash that let me know this could ultimately fail in the exact right circumstances. Although the use of std::mutex caused issues (crashes) when used in filterFile and older MSVC++ runtime libs, it appears to be fine when used in this class: no crash observed when run on Windows 7.
