We're running Dovecot with SOLR Lucene 5.5 and we have several errors like
badMessage: 414 for HttpChannelOverHttp@5216da8e{r=0,c=false,a=IDLE,uri=-} 20.5.2016, 14:10:16
and
URI is too large >8192
in our solr-logfile.
I don't know if this is a problem in SOLR or in Dovecot, so I just bring it to your attention.

Maybe increasing maxHttpHeaderSize="65536" in your Tomcat Connector definition in /etc/tomcat7/server.xml helps. But as far as I know the default URI limit should be 32k, not 8k... Do you have a HTTP proxy in front of your SOLR servers? Apache has a request limit of 8k for example... http://httpd.apache.org/docs/current/mod/core.html#limitrequestline
Problem seems to be that some clients (iOS?) are doing very strange SEARCH commands, with many OR conditions, which results in very long search requests to SOLR...
