Symptoms

Due to a mistaken internal object-size conversion, the statistical data used by the IP::stats iRule command reports a negative number when the data exceeds 2**31.

Impact

iRules cannot rely on the validity of the IP::stats counters when more than 2 gigabytes have been transferred.

Conditions

Transferring more than 2 gigabytes or 2 billion packets on a connection that then uses IP::stats commands in an iRule will show a negative number.

Workaround

Upgrade to a fixed version.

Fix Information

iRules now uses a 64-bit object
