It will show an error message and resend it in every seconds.
I have no idea whether it occurred by killing the process memcached.
I kill the process is because to NullpointException in the project witch using Spring-Data-Couchbase 1.3.2.RELEASE depends on couchbase-cleint 1.4.7, memcached 2.11.6.
It happen randomly,not every save() method with spring interface CrudRepository would cause.
java.lang.NullPointerException: null

A global variable ‘status’ is null.
In order to solve this issue, I kill the process and it will restart automatically.
After restart, this NullpointException disappear, everything can work.
Then the disk overview in the console cannot show correctly.

Total Cluster Storage (0 B)
In Use (3.44 GB)
Other Data (0 B)

I did not know whether has the relations with unusual status in couchbase.
Is there any recommendation to deal with it or any more info I can provide?
Should I re-install the couchbase? because of these issues can not be found in another machine(same version).
