* more Signed-off-by: Miek Gieben <miek@miek.nl> * Remove server addr from the context This was added twice, just leave the server which also holds the address. Conflicts with #2719 but should be easy to fix. Signed-off-by: Miek Gieben <miek@miek.nl> * doesn't need server context Signed-off-by: Miek Gieben <miek@miek.nl>
