[Bug 591823] Re: "File descriptor \d+ (\S+) leaked on lvs invocation."

[Ville Koskinen]

For what it's worth, I encountered this warning message in Debian
Wheezy. The reason I'm reporting it here is because I only got the
warning message after installing memtest86+. Previously, updating the
kernel or rerunning the GRUB configuration did not cause the warning to
appear. After installing memtest86+, it's as described:

File descriptor 3 (pipe:[200228]) leaked on lvs invocation. Parent PID
4167: /bin/sh

Wheezy does not install memtest86+ by default, while Ubuntu does (at
least when I last used it). Could this be part of the problem or the
solution?

  This is a slightly controversial bug and it's not yet fixed either way
  (aka fix not to leak file descriptors or stop warning by default)
