Known Affected Versions:
12.0.0, 12.0.0 HF1, 12.0.0 HF2, 12.0.0 HF3, 12.0.0 HF4

Fixed In:

Opened: Jan 15, 2016
Severity: 3-Major

Symptoms

When HTTP enters Fallback mode it may trigger aborts when it encounters unexpected events. Other profiles expect to be aborted once, not more than once. If enough unexpected conditions occur in the same flow it is possible to confuse other filters below HTTP.

Impact

Unknown

Conditions

HTTP enters Fallback mode. Complex iRules or other profiles cause unexpected events to occur in the HTTP filter. These events cause more than one abort to be processed at the same time.

Workaround

None

Fix Information

HTTP Fallback mode no longer generates more than one abort when it encounters unexpected events.
