Red Hat Bugzilla – Bug 1288888
20 GB virtual memory usage?
Last modified: 2016-12-20 11:42:17 EST
* recently a OOM killer for Firefox
* htop shows currently 20.3 GB VIRT memory
* htop shows currently 638 MB RES memory
are the upstream developers drunken?
4 open tabs - hell i run complete operating systems with that ressources
the tabs in "page information" for "livehttpheaders" and "view cookies" extensions are empty
I have the same observation about very high virtual memory being reported while physical memory is reasonable. I will try to paste the salient lines from "top" here, if not readable I will try to make an attachment.
As you can see, not ALL firefox instances report high virtual memory usage.
Likewise, I have seen high virtual memory in version firefox 42.0 and in firefox 44.0.2, although in my top listing below it is only v44.0.2 that is exhibiting the symptom at the moment.

The processes marked with * have the large virtual memory. Note also that 28.513g is larger than my physical memory usage of
27,709,260k, but there is 0 swap used. So the numbers are quite inconsistent.
According to Harald, above, the symptom is also in fc23, so please do not ignore just because my particular case is in fc19/x64/.

This message is a reminder that Fedora 23 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 23. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora 'version'
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.
Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 23 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 23 changed to end-of-life (EOL) status on 2016-12-20. Fedora 23 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
