Re: [Bug 1327360] Re: xfs_btree_cur leak


Thanks!  We'd appreciate some time, as we have largely dealt with the
issue by upgrading to the 3.8.0 backport kernel, and I'm going on
vacation next week.  I'll see if one of my colleagues can get back to

  xfs_btree_cur leak

Status in “linux” package in Ubuntu:
  In Progress

Bug description:
  There appears to be a kernel memory leak of xfs_btree_cur in recent
  Precise kernels (3.2.0-45 and -63 are affected, for sure).   The slab
  can grow unbounded; we've seen it grow larger than 32GB via slabtop.
  The affected hosts have XFS mounted on / (root filesystem).

  We have another host running 3.2.0-38 in which we do not see this
  problem (it has a 37TB XFS filesystem mounted, but not on root).

  Upgrading to the latest 3.8.0-41 kernel via linux-generic-lts-raring
  seems to resolve the issue.
