Memcached self maintenance

[Boti9717]

When I try to run my project in eclipse, in console appears this:
[MaintThread] DEBUG com.meetup.memcached.SockIOPool - ++++ Starting self maintenance....
[MaintThread] DEBUG com.meetup.memcached.SockIOPool - ++++ Size of avail pool for host (localhost:11211) = 10
[MaintThread] DEBUG com.meetup.memcached.SockIOPool - ++++ Size of avail pool for host (localhost:11211) = 10
[MaintThread] DEBUG com.meetup.memcached.SockIOPool - ++++ Size of busy pool for host (localhost:11211) = 0
[MaintThread] DEBUG com.meetup.memcached.SockIOPool - +++ ending self maintenance.
It worked for weeks and I not changed nothing.
