Issue

  • Liferay instance node goes into hang mode and the following error appears:
    HikariPool-1 - Failed to validate connection ... (This connection has been closed.)
    ...
    Possibly consider using a shorter maxLifetime value.

Environment

  • DXP 7.4
  • PostgreSQL

Resolution

  • We strongly recommend setting this value, and it should be several seconds shorter than any database or infrastructure imposed connection time limit.
    • The minimum allowed value is 30000ms (30 seconds)

Additional Information

  • The maxLifetime property controls the maximum lifetime of a connection in the pool. An in-use connection will never be retired, only when it is closed will it then be removed. On a connection-by-connection basis, minor negative attenuation is applied to avoid mass-extinction in the pool. A value of 0 indicates no maximum lifetime (infinite lifetime), but still subject to the idleTimeout setting.
  • References for related to the default values and modifications to the DB connection count and maxLifetime properties:
