[GitHub] [trafficserver] paulo opened a new issue, #9279: Failed assertion when `proxy.config.http.cache.open_write_fail_action` set to 5
paulo opened a new issue, #9279:
URL: https://github.com/apache/trafficserver/issues/9279
I've been pretty easily able to reproduce the following trace when `proxy.config.http.cache.open_write_fail_action` is set to 5 (with r[ead while writer](https://docs.trafficserver.apache.org/en/9.1.x/admin-guide/configuration/cache-basics.en.html#read-while-writer) enabled as well).
```
Fatal: HttpCacheSM.cc:101: failed assertion `captive_action.cancelled == 0`

```
Can reproduce it in both 9.1.3 and 9.1.4 with the following scenario:
- Client that can make up to 20 parallel HTTP/1.1 GET requests.
- Client requests get cancelled after writing the headers.
- Slow origin (can take up to 5 seconds to stream the entire payload, which in my tests is just 20 bytes).
Can't reproduce it with any other `proxy.config.http.cache.open_write_fail_action` setting.

I got this to show up during testing august 2023 in ats master. Was getting crashes with simulating thundering herd with simulated manifest, max-age=0 provided the best way to recreate the crash. Definitely related to stale assets. Unfortunately the crash just cleared up while I was working on it, trying to recreate it again.
