    Description

      Hello

      Since few months i try to upgrade MongoDB from 2.4 to 2.6 and I have problems.

      I have tried some 2.6 versions

      • Load average problem
      • Lock increase ( < 3% in 2.4 and > 10% in 2.6 )
      • The connections are not closed
        In Mongo 2.4 everything work fine

      My Configuration :
      3 servers in ReplicaSet

      OS: Debian Wheezy 64bit
      Data size: 26GB

      I have tried to upgrade one server or the 3 servers in the same time
      For the upgrade, i'm using :
      https://docs.mongodb.org/manual/release-notes/2.6-upgrade/

      I can't find any information in logs.

      Configuration used for 2.6 upgrade :

      dbpath=/home/data/db/
      logpath=/var/log/mongodb/mongodb.log
      logappend=true
      port = 10001
      cpu = true
      replSet = replset

      The configuration does not change between upgrades
      Servers have the necessary resource (No swap, ...)
      We tried to upgrade the drivers for applications that connect to MongoDB but there is no change.

      Do you have an idea ?
