Opened: Oct 03, 2018

Severity: 3-Major

Symptoms

gtmd leaks memory every time an auto-rolling DNSSEC Key on a DNSSEC Zone expires or rolls-over.

Impact

gtmd leaks memory every time an auto-rolling DNSSEC Key on a DNSSEC Zone expires or rolls-over.

Conditions

Auto-rolling DNSSEC Keys are associated with a DNSSEC Zone.

Workaround

The user can modify their DNSSEC Keys to be non-rolling/static dnssec keys. Also gtmd can be restarted to temporarily correct the memory leak. But this workaround is not recommended except during a scheduled maintenance window or unless traffic processing seems to be impacted by gtmd memory usage (unlikely scenario).

Fix Information

None
