We have updated our java mongo driver from 2.13.0 to 3.0.2, and since then, we have tons of "killcursors: found 0 of 1" in logs on our secondary servers

Before the change, we had around 500 logs per hours of it :

$ sudo grep 2015-06-09T14 /var/log/mongodb/mongodb.log | grep -c killcursors
511

since the change, we have around 150 times more of this log :

sudo grep 2015-06-09T18 /var/log/mongodb/mongodb.log | grep -c killcursors
78043

After the rollback, these logs disapeared
