[Bug 1249343] Re: Packagekitd eating RAM, CPU

[Quinn Balazs]

If you would, please collect memory forensics using valgrind. Use the
instructions here: https://wiki.ubuntu.com/Valgrind, and post the
resultant valgrind.log(s). After this has been done and uploaded, set
the status here back to new and someone will take a look at it.

Thanks,
Quinn Balazs

Title:
  Packagekitd eating RAM, CPU

Status in “packagekit” package in Ubuntu:
  Incomplete

Bug description:
  Since updating to saucy, packagekitd seems to eat all my memory,
  turning computer sluggish. If I kill it it respawns soon and quickly
  eats half the RAM. I have seen even seen VM size > 10G, with resident
  set sizes of 1-3G, way too much for a computer with 4G of RAM.

  I do not know how to debug the issue; however looking at the
  /proc/pid/fd shows something even more dubious, there are 578 open
  file descriptors to files in /var; all apt-lists and
  /var/lib/dpkg/status are opened with 12 filedescriptors? Also,
  /var/cache/apt/pkgcache.bin seems to be memmapped quite some many
  times:
