    Description

      Hello Guys,

      Memcached worked fine since 2 months until yesterday (when my cbtransfer command reach 47%).
      It now takes 90% of CPU (there is no activity, no get/set request), I did a collect_information, where can I upoad it (70mo) ?

      I stopped my cbtransfer, stopped couchbase (service couchbase-server stop), memcached has to be kill manually as it doesn't respond to couchbase kill signal.
      On restart (service couchbase-server start), memcached re-takes 87% of CPU ...
      I did stop/start 3 times, always the same issue, memcached take all the CPU.

      We have 200 millions of indexed items and I can't reinstall everything.

      What do you suggest ? How can I help you investigate of this ?
