I'm seeing the errors below when running the StreamExpressionTest. I suspect
it's related to this ticket. I've been adding tests the past couple of days but
only started seeing this today:

> Key: SOLR-10524
> URL: https://issues.apache.org/jira/browse/SOLR-10524
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Reporter: Erick Erickson
> Attachments: SOLR-10524-NPE-fix.patch, SOLR-10524.patch,

>
> There are several JIRAs (I'll link in a second) about trying to be more
> efficient about processing overseer messages as the overseer can become a
> bottleneck, especially with very large numbers of replicas in a cluster. One
> of the approaches mentioned near the end of SOLR-5872 (15-Mar) was to "read
> large no:of items say 10000. put them into in memory buckets and feed them
> into overseer....".
> This JIRA is to break out that part of the discussion as it might be an easy
> win whereas "eliminating the Overseer queue" would be quite an undertaking.
