Known Issues in EMQX 5.9

e5.9.0

Since version	Issue	Workaround	Status
5.0.0	Node Crash if Linux monotonic clock steps backward In certain virtual Linux environments, the operating system is unable to keep the clocks monotonic, which may cause Erlang VM to exit with the message OS monotonic time stepped backwards!.	For such environments, you may set the +c flag to false in etc/vm.args.
5.3.0	Limitation in SAML-Based SSO EMQX Dashboard supports Single Sign-On based on the Security Assertion Markup Language (SAML) 2.0 standard and integrates with Okta and OneLogin as identity providers. However, the SAML-based SSO currently does not support a certificate signature verification mechanism and is incompatible with Azure Entra ID due to its complexity.	-
