kyototycoonをmemcachedモードで使う

kyototycoonをmemcachedモードで使ったときの不思議な現象が出たのでメモ

使用したバージョンはこれ

kyotocabinet-1.2.76

kyototycoon-0.9.56

MacOS10.8

まずはOKパターン

$ /usr/local/bin/ktserver -host 127.0.0.1 -th 2 -plsv /usr/local/libexec/ktplugservmemc.dylib -plex 'opts=f' ./ktserver.kch >> ./ktserver.log
$ telnet localhost 11211
Trying ::1...
telnet: connect to address ::1: Connection refused
Trying 127.0.0.1...

NGパターン

$ /usr/local/bin/ktserver -host 127.0.0.1 -port 11211 -th 2 -plsv /usr/local/libexec/ktplugservmemc.dylib -plex opts=f ./ktserver.kch

ポートを明示的に指定すると落ちてしまう
