Leif Hedstrom updated TS-4009:
------------------------------
Assignee: Phil Sorber
> stale_while_revalidate crash
> ----------------------------
>
> Key: TS-4009
> URL: https://issues.apache.org/jira/browse/TS-4009
> Project: Traffic Server
> Issue Type: Bug
> Components: Plugins
> Affects Versions: 6.0.0
> Reporter: Christoph Keller
> Assignee: Phil Sorber
> Labels: regression
> Fix For: 6.1.0
>
>
> Since 6.0 stale_while_revalidate-plugin crashes after serving a stale
> document while trying to get the new one. Can reproduce this issue with 6.0.x
> and master branch using the provided testserver. 5.3.x works fine. Doesn't
> look like that issue is up to some changes in the plugin-code so i guess it's
> an issue in the core code.

> "consume_cont = TSContCreate(consume_resource, NULL);" in fetch_resource
> In case i create a new TSMutex and pass it to this call it seems to work.
> Trying to make a patch for that now.
> I guess it is broken due to these changes:
