Bug#893685: Segfault after higher number of connections
Package: siege Version: 4.0.2-1.1+b1 Followup-For: Bug #893685 Dear Maintainer, As I was having issues with Siege, I tried to contact its maintainer on GitHub: https://github.com/JoeDog/siege/issues/141#issuecomment-552889047 I managed to get it working on Debian buster, where Siege is in v4.0.4 instead of 4.0.2. Menwhile, project maintainer says he's not dealing with Debian packages. Eventually, I found a similar bug logged to Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=893685 Last message would suggest Victor Martinez found a possible fix, though there hasn't been much feedback since then, while that faulty package is still being distributed to Stretch users. What can we do next?

Sorry for the late reply. Thanks for the additional details. I will look for the fix in upstream commit history, and will work to add the version in debian unstable to the backports for stable. Regards, Josue

Bug#893685: Segfault after higher number of connections
Package: siege Version: 4.0.2-1.1+b1 When running siege, always getting the segfault after more than 700 connections were made. Tests made on nonTLS connections with GET method only (Debian repository URIs). Siege just stops receiving data. There are seen high receive queues on siege side and send queues on server side. Installing the unstable version fixed the issue (downloading deb and "dpkg -i"). Maybe related to upstream bug https://github.com/JoeDog/siege/issues/76 Peter
