Sudheer Vinukonda created TS-2782:
-------------------------------------
Summary: ats crash in master in HdrHeap::inherit_string_heaps
Key: TS-2782
URL: https://issues.apache.org/jira/browse/TS-2782
Project: Traffic Server
Issue Type: Bug
Components: Core
Reporter: Sudheer Vinukonda
When testing master on production hosts, noticed the below crash occuring
repeatedly every time ats version is changed. This crash stops happening after
clearing the cache. This needs further investigation, but, I remember a
discussion between briang and zwoop about duplicate string fields in HdrHeap.
Not sure if this core is related to that. Would appreciate if briang or zwoop
can comment. Thank you.
