Jan Høydahl commented on SOLR-12814:
------------------------------------
I wonder if this is the MetricsHistoryHandler that issues that request? If you
simply sit waiting for a minute without invoking the Cloud->Nodes tab at all,
you'll get things like this in the log:

> Project: Solr
> Issue Type: Bug
> Security Level: Public(Default Security Level. Issues are Public)
> Components: metrics, SolrCloud
> Affects Versions: 7.5
> Environment: 3x zookeeper and 3x solr cloud servers,
> 50 test collections with 0 data in them

> If you have a lot of collections, like 50 or more, the new metrics page in
> version 7.5 can't run its queries because the default
> solr.jetty.request.header.size and solr.jetty.response.header.size values are
> too small.
> If I up the header values from 8192 to 65536 the commands will work.
> command to change the defaults:
