Sudheer Vinukonda created TS-2776:
-------------------------------------
Summary: Core dump inside openssl library
Key: TS-2776
URL: https://issues.apache.org/jira/browse/TS-2776
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Sudheer Vinukonda
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.
