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 of problem:
When looking into glibc/nscd crash I hit the following error:
`info thread' or `thread apply all bt' command are printing
"Cannot find new threads: generic error"
Version-Release number of selected component (if applicable):
gdb-7.2-53.el6 is BROKEN (6.3)
gdb-7.2-47.el6 is BROKEN (6.1)
gdb-7.1-29.el6 is OK (6.0.z)
tried only on x86_64
How reproducible:
I have core file on which I can reproduce it all the time. It happened on live nscd as well, but I'm not sure about reproducibility. Unfortunately the core file has 140 MB so I don't want to attach it to the bugzilla.
Steps to Reproduce:
1. gdb /usr/sbin/nscd core.nscd
2. info threads
Actual results:
Cannot find new threads: generic error
Expected results:
