High cpu memcached process
We use couchbase 2.0 with a "couchbase" bucket (no views) as a persistent memcached.
The memcached process cpu usage is really high (one core always in 100%).
In this thread: http://www.couchbase.com/forums/thread/high-cpu-usage-memcached-process-... explain that there is a fix in 2.0.1 but we have upgraded the server, and after a few hours of normal operation, the cpu usage spike up again as in 2.0.0.
BTW, I can't post in that thread, the spam filter blocks my post...
