Testing ATS with the ab command you gave I did see a coredump on the active queue management and fixed the bug (https://issues.apache.org/jira/browse/TS-3953 <https://issues.apache.org/jira/browse/TS-3953>). However, the coredump I was getting had a different backtrace.
I ran ab many times with this fix and haven’t seen any other coredumps. -Bryan > On Sep 28, 2015, at 11:43 AM, Bryan Call <[email protected]> wrote: > > I will see if I can reproduce it today.
