Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

as the up backtrace what confused me is that
entry->type is not correct, I don't known how to reproduce it.
It looks like the threads didn't do well with the xcache

Hi Yogazhao,
Unfortunately, this BZ cannot be serviced in its current form.
Version-Release number of selected component (if applicable):
openvswitch:2.3.1
linux kernel:4.4.110
How reproducible:
don't known how to reproduce
OVS 2.3.1 with 4.4.110 kernel is not a supported combination.
Currently we are supporting OVS with our layered products OSP, OSE, or RHV and they are not using this combination
Plus you mention the issues is not reproducible.
Can I request you to please work with our customer support team and file an official ticket with them. And they can guide you further.
Thanks
If I am missing something please do let me know, and we will try to look at it again
RHEL7.5 + OVS 2.9 + OSP 13. This is one supported combination.
I think we should close this BZ for now, and open a new one if you have issues with supported versions of the RH SW. Does that make sense?
