      Description

      Hi,

      OS - Scientific Linux release 6.10 (Carbon)

      After upgrading to cvmfs-2.6.2-1.el6.x86_64  the /usr/bin/cvmfs2 appears to have a significant memory leak. 

      Starting from a clean cache area (nothing in it at all).

      The command - cvmfs_config probe

      triggers increasing memory use of /usr/bin/cvmfs2

      This behavior is not seen in version 2.5.2
