Steve Rowe commented on SOLR-5652:
----------------------------------
I tried reproducing the other four seeds I found by running each of them ten
times, but they all passed.
Here's the output of {{egrep 'Throwable|SOLR\-5652: \[\^(]'}} over the other
four failed trials' log files:

{noformat}
The trial #358 failure has sort=double_dv_last+*asc*
bq. One thing that jumps out at me here is that in this failure the doc in
question (93) doesn't have a value for the int_dv_last field being sorted on
This is also true for all of the above failures, and for the failure in the
attached {{129.log}}.

> Twice now, Uwe's jenkins has encountered a "walk already seen ..." assertion
> failure from DistribCursorPagingTest that I've been unable to fathom, let
> alone reproduce (although sarowe was able to trigger a similar,
> non-reproducible seed, failure on his machine)
> Using this as a tracking issue to try and make sense of it.
> Summary of things noticed so far (in 3 failures):
> * So far only seen on http://jenkins.thetaphi.de & sarowe's mac
> * So far only seen on MacOSX
> * So far only seen on branch 4x
> * So far seen on both Java6 and Java7
> * fails occured in first block of randomized testing:
> ** we've indexed a small number of randomized docs
> ** we're explicitly looping over every field and sorting in both directions
> * fails were both when doing a "desc" sorting on one of the "\*_dv_last" or
> "\*_dv_first" fields (docValues=true, either sortMissingLast=true OR
> sortMissingFirst=true)
> ** sort on same field asc has always worked fine just before this (fields are
> in arbitrary order, but "asc" always tried before "desc")
> ** sorting on some other random fields has sometimes been tried before this
> and worked
> (specifics of each failure seen in the wild recorded in comments)
