Package: libblockdev-swap2
Version: 2.20-6
Severity: grave
Tags: a11y
Justification: renders package unusable
Dear Maintainer,
Not sure if I choose the right package.
* What led up to the situation?
When loading a tif image with feh of 100MB or (which was the next image) 749MB
the system (Intel Pentium G630 with 4GB DDR3) freezes.
/etc/sysctl.conf
# swappines
vm.swappiness = 10
* What exactly did you do (or not do) that was effective (or ineffective)?
I presume it has something to do with swapping. I experience the same when
I have 15+ tabs open in Firefox (latest version)
When after a long wait the system comes out of the freeze and is usable again
the
system remains slower than before the view attempt of the image.
When touching a 100MB tif image in Thunar the system freezes. It does not
recover
anymore -> hit the reset button
* What was the outcome of this action?
Waiting a long time or even hitting the reset button
* What outcome did you expect instead?
No system freezes or slugginess
Release swap when it is not needed anymore so the system stayes responsive
even after heavy swapping
Some ideas for a solution:
Get a message with a choice that swap can not handle the amount of data
Make swap abandon the operation
Give the user some sort of control. Do not let him get in a freeze /
sluggines situation without recovery in an acceptable time
* Some thoughts
Maybe I did something wrong.
