Symptoms: NAT Stateful forces the router to crash when there is heavy traffic exchanged between 
two peer SNAT routers. When active routers come back and a DUMP request process occurs at the 
same time, entries time out all together. This generates a large number of ACK packet exchanges 
and the actual data structure which stores these ACKs cannot handle this amount.

Conditions: This symptom has been observed with SNAT Active/Standby configuration using the 
SNAT UDP option. When the NAT table has a size larger than 10000 entries, all entries of the table 
time out together. This timeout generates high density of packet exchange due to SNAT flow control 
mechanism.

Workaround: There is no workaround.

Symptoms: Bidirectional DTR does not function. The output of the show dialer command shows 
the incorrect dialer type.

Conditions: This symptom is observed on a Cisco 3660 that runs Cisco IOS interim 
Release 12.3(12.9)T.

Workaround: There is no workaround.

Conditions: This symptom is observed on a Cisco 3745 that runs Cisco IOS Release 12.4(1).
