---------------------------------------
[~jpountz][~thetaphi][~mikemccand] Any insights here as the error is coming
from Lucene?

> i.e. Core creation fails because there was some confusion between long and

> If there is a data issue then somehow it should communicate it with an

> *UPDATE*:
> Another issue I see with the above problem is that solr cluster is completely
> inaccessible.
> Solr-UI is also not coming up. I restarted the Solr servers and they refuse
> to recover.
> I am not even able to delete the collections and create them afresh.
> It seems the only way out is to do an *rm -rf* and re-install
> Note that it is not related to network as I can ssh to the Solr machines and
> send messages to other Solr machines using nc
> \\
> \\
> *UPDATE 2*:
> I had a 24 node cluster with 2 collections.
> Each collection used 6 nodes and had 2 shard, 3 replica configuration.
> So 12 nodes used out of 24 nodes.
> Rest 12 nodes had Solr running with same zookeeper but no collections/cores.
> After the above errors begin to happen, Solr-UI of all 24 nodes became
> unresponsive!
> So I tried the delete-collection API from the command line - no response.
> Ultimately I ran the delete-collection from the command line in a loop and it
> deleted a part of the collection.
> Then I had to manually delete the *<coreName>/data/index/write.lock* file on
> some nodes to purge those bad collections.
> Its been a few hours since then. There are no collections and still few nodes
> are unresponsive with following messages in the logs:

> It looks like a serious stability problem to me.
