Cisco Cisco IOS Software Release 12.4(4)T

Workaround: There is no workaround to prevent the symptom from occurring. When the symptom 
has occurred, enter the no virtual-template subinterface command, save the configuration to the 
startup configuration, and reload the router. 

CSCin94072

Symptoms: Bundle master should have PVC bundle adjacency length of zero and adjacency should 
be complete. However, the bundle master is showing an encapsulation length of 12.

Conditions: The symptoms are observed on a Cisco 7600 series router and other distributed 
platforms.

Workaround: There is no workaround. 

CSCsa73179

Symptoms: Memory corruption, possibly leading to a crash or other undesired behavior, can occur 
when the no default-information originate command is entered in router RIP configuration mode.

Conditions: This symptom occurs only if both the RIP routing protocol and the OSPF routing 
protocol are configured on a router.

Workaround: There is no workaround. 

CSCsf98956

Symptoms: Ping/telnet may fail with VRF configurations.

Conditions: This symptom is observed on a Cisco router that is configured for NAT with VRF 
configurations.

Workaround: There is no workaround. 

CSCsg03739

Symptoms: A memory leak may occur in the “Crypto” process.

Conditions: These leaks are independent of any HW accelerator. This bug is not platform dependant.

Workaround: There is no workaround. 

CSCsg44748

Symptoms: A Cisco IOS VoIP gateway configured for IPIPGW (CUBE) functionality may crash.

Conditions: A gateway configured for IPIPGW functionality with the allow-connections command 
under voice service voip will crash under rare conditions while processing VoIP calls.

This has been found to occur in some scenarios where a single voip call loops (meaning the call is 
from the IPIPGW back to the same IPIPGW) through the IPIPGW.

When this occurs, the following error message may be noticed:

%SYS-6-STACKLOW: Stack for level Network interfaces running low, 0/9000

Workaround: The workaround is to track down the source of the call looping and correct the problem 
there.

The other possible workaround is to introduce another termination point in the RTP packet flow 
beside the IPIPGW. For example, if interworking with Cisco Unified Communications Manager 
(Callmanager), an MTP resource may be used to prevent this loop. 

CSCsg92618

Symptoms: Entering the crypto key zeroize rsa command causes traceback.

Conditions: This symptom is observed in router loaded with the Cisco IOS software image.

Workaround: There is no workaround.
