Mongo DB 3.0 Full Text Search Memory Leak

[zhongxi yuan]

Hi All,

Recently I update my DB from2.6 to 3.0.   I find when I execute  command 

db.DeviceDataCurr.find({$text:{$search:"hostname"}},{_id:1}).limit(10)

via mongo.exe, the Server memory will increase,  The server died after I looped run this command.

I tried many times and found that both mmapv1 and wiredtiger have this promblem.

I also tried v2.6,  It works fine.

Hope your response.

there are some db log
