a day later the process caused 400% cpu load so i restarted it ...

I had the same problem with 1.4.15-9 from januar 2016.

I could work around this with memcached 1.4.25 from a diffrent Centos machine where i build it manualy - i replaced /usr/bin/memcached 1.4.15 with 1.4.25 from this host and this version was running for 220 days without problems.
