Hello, it seems the issues is related to tls/ssl session caching... A workaround is to start perdition via inetd (though less performing). This way each process serves only one request and then dies (emptying tls cache). This patch worked for me. Waiting for a clean solutions. Bests Giorgio -- "Le cose belle della vita Ing.
