RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Victor Toso 2015-10-09 18:59:28 UTC 
+++ This bug was initially created as a clone of Bug #1264156 +++

Description of problem:
I'm seeing ~100MB/s memory leak in either virt-viewer or virt-manager when redirecting a usb-webcam.

Version-Release number of selected component (if applicable):
Client: virt-viewer or virt-manager on f22
spice-gtk-debuginfo-0.29-1.fc22.x86_64
spice-gtk-0.29-1.fc22.x86_64
spice-gtk3-0.29-1.fc22.x86_64
spice-protocol-0.12.7-2.fc21.noarch
spice-glib-devel-0.29-1.fc22.x86_64
spice-glib-0.29-1.fc22.x86_64
spice-server-devel-0.12.5-6.fc22.x86_64
spice-gtk-tools-0.29-1.fc22.x86_64
spice-debuginfo-0.12.5-5.fc22.x86_64
spice-vdagent-0.15.0-3.fc22.x86_64
spice-server-0.12.5-6.fc22.x86_64
usbredir-0.7-3.fc22.x86_64
virt-viewer-2.0-1.fc22.x86_64

guest: RHEL7.1
host: RHEL6
spice-server-0.12.4-12.el6_7.1.x86_64
spice-gtk-python-0.26-4.el6.x86_64
spice-glib-0.26-4.el6.x86_64
spice-gtk-0.26-4.el6.x86_64



How reproducible:
100%

Steps to Reproduce:
1. Start virt-viewer or virt-manager on your local machine
2. Connect to a remote host running the guest
3. Perform a usbredir via spice of a cheap webcam (0c45:62f0 is the USB model in my case) to a usb 2 card on the guest
4. Start 'cheese' in the guest

Actual results:
~ 100MB/s leak

Expected results:
No leak.

Note: The connection between the host/client may be relevant:

host - somewhere in Boston
client - UK; on the end of a 50 down/3 MBps up cable link
with a VPN and the atlantic in between.

Thanks for the report + massif!
I can reproduce this on slow connection. Working on it!
