Solução: 

Procure o arquivo "web.xml" do "manager application" (normalmente encontra-se em /tomcat7/webapps/manager/WEB-INF/web.xml)

Procure os parametros: "max-file-size" e "max-request-size"

<multipart-config>
<!– 50MB max –>
<max-file-size>52428800</max-file-size>
<max-request-size>52428800</max-request-size>
<file-size-threshold>0</file-size-threshold>
</multipart-config>

E aumente os valores do "max-file-size" e "max-request-size".
