[jira] [Created] (TS-2147) rfc5861 plugin causes a segfault
Corey Cossentino created TS-2147:
------------------------------------
Summary: rfc5861 plugin causes a segfault
Key: TS-2147
URL: https://issues.apache.org/jira/browse/TS-2147
Project: Traffic Server
Issue Type: Bug
Components: Plugins
Reporter: Corey Cossentino
When using the rfc5861 plugin, the server will segfault when a cache lookup is stale.
To reproduce: using the Node.js test server provided with the plugin, make a request, then make a second request for the same URL after at least five seconds.
[TrafficServer] using root directory '/usr/local'
