[Dave Walker (davewalker)]

Untested patch which claims to resolve the issue as raised, however there may be additional issues.

[Colin Watson (cjwatson)]

There's already stuff in main() which sets each of settings.port and settings.udpport to the other if only one is specified. I think it's safer to just drop the dead code.

[Launchpad Janitor (janitor)]

This bug was fixed in the package memcached - 1.4.5-1ubuntu3

---------------
memcached (1.4.5-1ubuntu3) oneiric; urgency=low
