Description Sarvesh Pandit 2016-06-20 09:57:21 UTC

Description of problem:
Internet Explorer 11 and the RHEV Manager - memory leak. Using Internet Explorer with the RHEV Manager Administration Tool, slowly consumes more and more memory until the system becomes unusable.

With a single tab open on the RHEV Manager page, IE is currently using 1.5Gb of RAM and increasing.  This makes the RHEV Manager extremely slow and difficult to use.

a. Client OS version (32/64 bit)
- Windows 7 64-bit.  3 x virtual CPU w/ 3Gb of RAM

b. IE complete version
- 11.0.9600.18349, update versions 11.0.32 (KB160005)

c. Client hardware details such as make/model/product etc.
- Client is a virtual 64-bit Windows 7 system with 3 x virtual CPU and 3Gb of RAM


Version-Release number of selected component (if applicable):
rhevm-webadmin-portal-3.6.5.3-0.1.el6.noarch

How reproducible:

I have been experiencing huge memory consumption issues with IE 11 in general. In my case, I have a web app that can explode upwards of 1.7GB of memory consumption before IE just falls over. Other browsers do not appear to have the same problem.

It turns out that there was a bug in IE 11 related to runaway memory consumption.

Though it appears that this issue has been resolved by Microsoft, I am still experiencing the problem as of today. Perhaps these issues are related.
