Hi, I have post some mongrel2 1.8.0 crash trace on github. It's looks like a memory corruption.
I have test multiple version of ZMQ (2.2.0 + 2.2.x + 3.2.3) and the same issue occur. To reproduce the issue, - you need a host with a route to a ZMQ handler. - Open your favorite web browser (chrome & Firefox tested) and press F5 without release - Wait 1 or 2s - Mongrel2 is crashed Here some GDB trace https://github.com/zedshaw/mongrel2/issues/148#issuecomment-17997418
