I've compiled the Lenny package with your patch applied. Unfortunately,
I still get errors:

Aug 23 17:17:12 paulus collectd[10373]: memcached: poll(2) timed out
after 10 seconds.
Aug 23 17:17:12 paulus collectd[10373]: read-function of plugin
`memcached' failed. Will suspend it for 10 seconds.

Does this tell you anything more?

To test whether my memcached instance has problems I am running the
following script for a while:

while :
do
 echo quit | nc localhost 11211
 echo -n '.'
 sleep 1
done


Regards,

Joost
