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 Edjunior Barbosa Machado 2020-01-27 14:58:47 UTC 
Also reproducible with strace-4.24-4.el7 on RHEL-7.8-20200122.n.0 x86_64, ppc64 and ppc64le.

+++ This bug was initially created as a clone of Bug #1794490 +++

Description of problem:
Some of the ipc_* tests are occasionally failing on rhel-8.2 gcc-toolset-9-strace-5.1-4.el8. From the testsuite run output:

...
PASS: ipc_msgbuf-Xabbrev.gen.test
FAIL: ipc_msgbuf-Xraw.gen.test
PASS: ipc_msgbuf-Xverbose.gen.test
PASS: ipc_sem.gen.test
PASS: ipc_sem-Xabbrev.gen.test
PASS: ipc_sem-Xraw.gen.test
PASS: ipc_sem-Xverbose.gen.test
FAIL: ipc_shm.gen.test
FAIL: ipc_shm-Xabbrev.gen.test
PASS: ipc_shm-Xraw.gen.test
FAIL: ipc_shm-Xverbose.gen.test
...

For some reason, it is usually no longer reproducible when trying to rerun the testsuite. On the last testrun, it happened only in aarch64 and x86_64 (it ran successfully in s390x and ppc64le)

Version-Release number of selected component (if applicable):
gcc-toolset-9-strace-5.1-4.el8

How reproducible:
Occasionally

Steps to Reproduce (as non-root user):
1. rpm -ivh gcc-toolset-9-strace-5.1-4.el8.src.rpm
2. rpmbuild -bc ~/rpmbuild/SPECS/strace.spec
3. cd ~/rpmbuild/BUILD/strace-*/
4. chmod u+x tests/*.test tests-m32/*.test tests-mx32/*.test
5. make -k check STRACE=/opt/rh/gcc-toolset-9/root/usr/bin/strace TIMEOUT_DURATION=1500

Actual results:
Occasional failures

Expected results:
No failures

Additional info:
RHEL-8.2.0-20200107.n.1
