Description

The Certificate Manager (certmgr) centrally handles TLS certificates (manual, Microsoft CA, Let's Encrypt/ACME) in certstore.nsf. CERTMGR_INTERVAL defines how often certmgr checks whether new certificate requests have arrived, expiring certificates need to be renewed, or pending renewals can be completed.
30 seconds is more than sufficient for production; during initial setup or debugging, the value can be temporarily reduced to 1–5 seconds.

Example configuration

CERTMGR_INTERVAL=30

Notes & pitfalls

  • Value in seconds.
  • For production servers, the default 30 is recommended – lower values increase load without benefit.
  • Complements CERTMGR_REQUEST_RENEWAL_DAYS, CertMgr_MaxRedirHTTPChallenge, CertMgr_NoVerifyHTTPChallenge.
  • A manual run can be triggered any time via tell certmgr run.
  • The change takes effect after a restart of certmgr (restart task certmgr).
