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.
When mod_revocator was enabled in httpd, every time httpd was stopped, mod_revocator leaked a semaphore. The provided patch fixes this issue, and mod_revocator no longer leaks semaphores upon httpd shutdowns. [BZ #1326841]
+++ This bug was initially created as a clone of Bug #1326840 +++
Description of problem:
mod_revocator leaks a semaphore every time httpd stops
Version-Release number of selected component (if applicable):
mod_revocator-1.0.3-10.el6.x86_64
How reproducible:
always
Steps to Reproduce:
1. restart httpd a few times
2.
3.
Actual results:
number of semaphores owned by apache increases
Expected results:
steady state.
Additional info:
The only instance of marking the semaphore for removal is in the shutdown of crlhelper. If the helper is not enabled, or even if it is there is no assurance that it will reach the end of the main block before being killed by its parent.
The main code contains the comment
/* The semaphore is removed in the helper program. This is because that
* program survives Apache reloads so the semaphore will as well.
*/
but again does not take account of shutdowns.
