Opened: Jun 23, 2017

Severity: 3-Major

Symptoms

When APM resumes an iRule event from an asynchronous session data lookup, the resumption fails due to a bad memory access resulting in a crash.

Impact

Traffic disrupted while tmm restarts.

Conditions

The following must be true for this to happen: - APM provisioned and licensed. - Use of APM iRule events. - Session data lookup from iRule events.

Workaround

None identified yet.

Fix Information

Fixed internals for 'session lookup' iRule command to prevent possible memory corruption with other iRule commands.
