Chapter 3. Bug fixes
This section describes bugs fixed in OpenShift sandboxed containers 1.6.
3.1. Sandboxed containers
Pod with io.katacontainers.config.hypervisor.virtio_fs_extra_args annotation does not start
Previously, virtiofsd did not accept the --thread-pool-size=16 option. This issue has been fixed in virtiofsd-1.5.0-1.el9_2.1, which is available in OpenShift Container Platform 4.13.24 and 4.14.4.
3.2. Performance and scaling
RHEL 9 compute nodes cause severe database workload performance degradation
Severe performance degradations were observed in database workloads running on Red Hat Enterprise Linux (RHEL) 9 compute nodes. This issue has been fixed in OpenShift Container Platform 4.13, 4.14, and 4.15.
Jira:KATA-2247
Excessive metric reporting causes Prometheus pods to fail
Previously, the kata_shim_netdev metric reported an excessively large volume of metrics, which caused Prometheus pods to fail with out of memory errors. In the current release, the issue has been fixed.
controller-manager pod fails with out of memory errors
Previously, when the OpenShift sandboxed containers Operator was deployed on a single-node, bare-metal cluster running OpenShift Container Platform 4.14.12, the controller-manager pod failed with out of memory errors. In the current release, the issue has been fixed by increasing the pod’s resources.
