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.
BIND incorrectly handled errors returned by dynamic databases (from dyndbAPI). Consequently, BIND could enter a deadlock situation on shutdown under certain circumstances. The dyndb API has been fixed not to cause a deadlock during BIND shutdown after the dynamic database returns an error, and BIND now shuts down normally in the described situation.
+++ This bug was initially created as a clone of Bug #1142150 +++
Description of problem:
bind hangs after reload/GSSAPI Error: The referenced context has expired (Success)
After a while (about once in a week) the bind daemon is in the state hang/zombie. The bind daemon seems to be present and accept requests from the clients, but is not answering any dns requests. Only killing the process with kill -9 can stop the daemon. After starting bind again, it works fine, until the problem occurs again.
Version-Release number of selected component (if applicable):
bind-9.9.4-14.el7.x86_64
How reproducible:
Everytime Logrotates runs.
Steps to Reproduce:
1. Configure IPA server with DNS
2. Wait till logrotate starts rotating.
Additional info:
It is related to https://fedorahosted.org/bind-dyndb-ldap/ticket/131
Steps to reproduce for QA:
1. install bind
2. build the attachment 966145[details] for your architecture
3. install the bind-dyndb-ldap package built from attachment 966145[details]
4. Add the following section to /etc/named.conf:
dynamic-db "my_db_name" {
library "ldap.so";
arg "uri ldap://ldap.example.com";
arg "base cn=dns, dc=example, dc=com";
arg "auth_method none";
};
5. export KRB5_KTNAME=/etc/named.keytab
6. run 'named -u named -fg' as root
7. named will start
8. run 'rndc reload' from another console and watch the error on output:
[root@localhost ~]# rndc reload
rndc: 'reload' failed: out of memory
9. press CTRL+C in the terminal you've started named or run 'rndc halt'
Actual result in 9.:
Named will freeze and the only way to stop it is to kill -9 it.
Expected result in 9. (and with attached patch):
Named will exit just normally.
