TS-3417: Fix MADV_DONTDUMP feature for reclaimable freelist
> Use madvise() with MADV_DONTDUMP option to limit core sizes
> -----------------------------------------------------------
>
> Key: TS-3417
> URL: https://issues.apache.org/jira/browse/TS-3417
> Project: Traffic Server
> Issue Type: Improvement
> Components: Core
> Reporter: Phil Sorber
> Assignee: Phil Sorber
> Fix For: 5.3.0
>
>
> When ATS crashes it often leaves behind very large core files, in the
> hundreds of gigabytes. A large percentage of these core files are useless
> data in the IO buffers. We can limit the pages that the kernel dumps with
> madvise().
> Note: This will only work on Linux 3.4+.
