I just scanned 30 documents with Simple Scan in 600 dpi and saved them
as png and got 2.1 gigabytes memory usage for tracker-extract (Ubuntu
Gnome 15.10). The memory was never deallocated. Simple Scan is missing
some usability features: it doesn't tell when it is actually processing
the image; you have to wait several seconds for the "Saving image"
notification to pop up. I don't know what the trigger case/root cause is
or what Simple Scan is doing (however, I know I'm not going to try
reproducing the scanning...).

Title:
  tracker-extract seems to briefly consume 1.5GB memory and slow
  computer right down

Status in tracker package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: tracker

  In normal operation of computer, very occasionally computer suddenly
  slows right down for about 45 seconds - mousepointer is very slow to
  respond to movement, and windows are too slow to respond to clicks.

  This has been hard to identify the cause because the computer is so
  slow to respond it's hard to get system monitor opened to see the
  offending process.  Anyway I've finally managed to view system-monitor
  within the 45 seconds, and it seems to be "tracker-extract" program
  that is responsible, that was consuming over 1.5GB of RAM on my
  machine.  It was hard to see though because the 45 seconds finished
  almost as soon as I'd viewed it, so it very quickly disappeared from
  the top of the process list when ranked by memory usage.

  So is "tracker-extract" the offending process?  Can it be made a
  little less hungry of Memory (+ CPU) please?

  I'm using Ubuntu 9.10 (karmic) 64 bit version on a 2.9GB machine.
