Full TDR-2 performance enhancements are not realized with some text files.

Link down entries in diagnostic log (TT2926)
There are occasional unexplained link down entries in the diagnostic log, however, connectivity is not affected.

Optimizable connections issues (TT2930)

WANJet 200 platform and hardware bypass mode (TT3079)
Occasionally, when the WANJet system on the WANJet 200 platform is under sustained, heavy load, the system might enter hardware bypass mode, where traffic is passed through and not optimized. To resolve this issue, reset the WANJet system.

Blocked traffic (TT3102)
If the WANJet appliance is under sustained, extremely heavy load processing a high rate of requests per second, the WANJet system might enter a state in which traffic is blocked. To resolve this issue, reset the WANJet system.
