[Bug 1398465] Re: Memory allocation failure, presumably in FUSE

We can now confirm that the issue does not happen with 4.0.9. This leads
to the assumption that the problem has either been fixed between 4.0 and
4.0.9, or, and I consider this much more likely, the problem was
introduced between 4.0 and 4.1 on the main branch.

Title:
  Memory allocation failure, presumably in FUSE

Status in linux package in Ubuntu:
  Invalid

Bug description:
  I just tried out linux-lts-utopic on trusty and hit a few backtraces.
  We make intensive use of FUSE and the FS operation I conducted on FUSE
  hung post-backtrace.

  So far I hit it once, so this is sort of the canary. I'll update the
  bug if I hit it again. Also I'll go and uninstall vmware-workstation.
