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...
