We received messages about core dumps that occur when siege is run with more than 700 threads. That’s a lot of threads, you guys! First things first — and this can’t be stressed enough — if you run siege with -c700, make sure your web server is configured with a pool of 700 threads. If you hit a pool of 256 threads with 700 users, all you’re gonna do is make a mess, mmmkay?

Now back to those core dumps. Here’s the thing: we’ve been unable to reproduce the problem but some diligent siegers have worked with us to get stack traces. As a result, we’ve added improved error handling and integrity checks in the problematic region. Your JoeDog would greatly appreciate if you could test version 3.1.0 release candidate 1. You can provide feedback here or by email, whichever you prefer.
