> Core dump inside openssl library
> --------------------------------
>
> Key: TS-2776
> URL: https://issues.apache.org/jira/browse/TS-2776
> Project: Traffic Server
> Issue Type: Bug
> Components: SPDY, SSL
> Reporter: Sudheer Vinukonda
> Assignee: Bryan Call
> Labels: spdy, yahoo
> Fix For: 5.0.0
>
>
> During production testing of SPDY (w/ ATS compiled from master repo), noticed
> the below core from open ssl library. This core showed up after fixing a few
> other core dumps and memory leaks (refer TS-2742, TS-2743, TS-2750, TS-2765,
> TS-2767 etc) and happened once so far, after running stable for 30+ hours on
> a production host.
