Mark Robert Miller commented on SOLR-17764:
-------------------------------------------

I honestly think its some kind of regression that its not retried. These kinds 
of tests always would have been very flakey otherwise, and I seem to remember 
making shutdown throw 503 so you could retry just for this issue. 

But who knows - if jetty is still stopped how it used to be in tests I don't 
see how this could be caused by graceful shutdown being added either or how it 
could be a relatively recent thing to pop up.

> Reviewing recent jenkins test failure metrics, I noticed that (Nightly) test 
> ChaosMonkeySafeLeaderWithPullReplicasTest started failing ~60% of the time 
> right around the time that SOLR-17744 was committed.
> Things i have observed:
>  * Seeds from failing runs seem to reliably reproduce the failure
>  ** These failures do *NOT* reproduce if i revert to just before SOLR-17744
>  * Ad-hoc testing I've done of seeds that do _not_ fail on first attempt seem 
> to reliably succeed on all subsequent attempts
>  ** Suggesting that the root cause is something deterministic in the 
> {{{}random(){}}}-ness of the test, and not something dependent on timing or 
> concurrency.
