[GitHub] [trafficserver] shinrich opened a new issue #6924: ATS9 crash
shinrich opened a new issue #6924:
URL: https://github.com/apache/trafficserver/issues/6924
I just did the experiment again of getting ASF 9.0.x and applying our local commits and outstanding PRs. Good news is the number of additions is around 8. The bad news is that it crashes within 5 minutes of production traffic with the following stack. In frame 3, vc->read.vio.cont is null and vc->write.vio.cont is not null but it doesn't dereference to anything interesting. The do_io_shutdown() will null out the continuation for the associated operation.
I did this experiment 9 days ago, and all was good.
I'm out tomorrow, so probably won't get back to debugging this until Monday.
```
