Description Deepu K S 2018-11-29 14:46:20 UTC 
Description of problem:
Since the 7.6 upgrade the gnome-shell process belonging to the logged in users uses lots of shared memory segments.
This gets increasing with time.

Version-Release number of selected component (if applicable):
Red Hat Enterprise Linux 7.6
mesa-dri-drivers-18.0.5-3.el7.x86_64
gnome-shell-3.28.3-6.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Login to GNOME session on RHEL 7.6
2. Open firefox and use it for some time with some tabs opened.
3. Download some images.
4. Check the shared memory segments of gnome-shell and firefox.
# ipcs -mp

Actual results:
# ipcs -mp | awk '{ if ($2 == "test" && $3 == 1234) print $_ }' | wc -l
967

The gnome-shell process 1234 of the user above has 967 attached shared memory segments after using for sometime.

Expected results:
No shm leaks or un-controlled increase of shm segments.
