The /UPGRADE command disconnects SSL connections instead of keeping them alive. This limitation (I doubt its possible to implement) should probably be docummented in /HELP UPGRADE.
tags 576766 + upstream confirmed thanks * Jon <jadevree@mtu.edu> [2010-04-07 06:46:32 CEST]: Somehow I had the impression that this is at least documented in a bug already - thanks for filing one. ;) There is this unfinished gnutls support patch which was thought to fix that issue, unfortunately noone did pick up the work. I'll try to get some patch for the help output prepared and submit it upstream - if they don't beat me with doing it themself in the meantime. ;) Have fun! Rhonda
