Description: This technical installation consumed all synchronizer threads: http://b3g4.gbif.org:8080/registry-ws/technical_installation/6064132c-f762-11e1-a439-00145eb45e9a The reason being that none of its endpoints are online, each one returning a 404.

After looking into the problem, Fede has found apache httpclient is hanging  with "http://www.siac.net.co/tapirlink/tapir.php/IAvH" since it is never returning.

Please see the attached screenshot, that demonstrates what the HIT user sees. ]]>

All the HttResponses should be consumed to release the current Http connection.
