Hi, We have just implemented the switch to HTTP NIO connector in the master branch: https://github.com/dogtagpki/pki/commit/3be16204bed2bf075fbe894135ca7d59c... See this page for explanation: http://www.dogtagpki.org/wiki/PKI_10.6_HTTP_NIO_Connector_Support If you have an existing PKI 10.6 (not 10.5) instance with HSM or Nuxwdog, follow this procedure when you pull the latest code from master branch: http://www.dogtagpki.org/wiki/Upgrading_PKI_10.5_to_PKI_10.6 Note: PKI 10.6 is still under development, it's not recommended to upgrade from PKI 10.5 at this point. Thanks. -- Endi S. Dewata
