Cluster scheduled job issues with Open ID Connect (OIDC)

Issue

  • A known issue related to clustering with environments using Open ID Connect has been identified wherein the number of scheduled jobs may be mismatched on each node. This may cause a performance impact, or a loss of user sessions if a node is taken offline or experiences a crash.
  • This is caused by the session data being stored as MEMORY_CLUSTERED jobs which can cause logins to become slower on environments using OIDC for authentication.

Environment

  • Liferay DXP 7.2, 7.3, 7.4

Resolution

  • As this is a known issue, it will be resolved in a future update.
  • We have a temporary fix available, so please create a Help Center ticket requesting a hotfix including LPS-162500 which will serve as a workaround while our Product Team builds a complete solution.

Additional Information

  • LPS-162500 - Performance impact by scheduler to refresh OIDC tokens. At the time of writing this article (2022 September), this report is still in review and will be included in a future software update.
