Cisco Cisco IOS Software Release 12.2

This section describes possibly unexpected behavior by Cisco IOS Release 12.2(24). All the caveats 
listed in this section are resolved in Cisco IOS Release 12.2(24). This section describes severity 1 and 2 
caveats and select severity 3 caveats.

The following information is provided for each caveat:

Symptoms: A description of what is observed when the caveat occurs. 

Conditions: The conditions under which the caveat has been known to occur. 

Workaround: Solutions, if available, to counteract the caveat.

CSCdz32659

Symptoms: Many memory allocation failure (MALLOCFAIL) messages may occur for a 
Cisco Discovery Protocol (CDP) process:

%SYS-2-MALLOCFAIL: Memory allocation of -1732547824 bytes failed from x605111F0, pool 

Processor, alignment 0 

-Process= "CDP Protocol", ipl= 0, pid= 42 

-Traceback= 602D5DF4 602D78A0 605111F8 60511078 6050EC88 6050E684 602D0E2C 602D0E18

Conditions: The symptom is observed on a Cisco 7513 that runs Cisco IOS Release 12.0(17)ST. The 
symptom may also occur on other Cisco 7500 series routers that run Release 12.0 S, 12.2 S, 12.3, 
or 12.3 T.

Workaround: To prevent the symptom from occurring again, disable CDP by entering the no cdp 
run global configuration command. 

CSCea33897

Symptoms: A Cisco router may generate a “%SYS-2-LINKED: Bad requeue” message. Following 
this message and after a time of operation, memory fragmentation occurs and the router reloads 
unexpectedly.

Conditions: This symptom is observed on a Cisco 7200 series that runs Cisco IOS 
Release 12.2(11)T. However, the symptom is not platform specific nor release specific.

Workaround: There is no workaround. 

CSCed09685

Symptoms: When command accounting is enabled, Cisco IOS routers will send the full text of each 
command to the ACS server. Though this information is sent to the server encrypted, the server will 
decrypt the packet and log these commands to the logfile in plain text. Thus sensitive information 
like passwords will be visible in the server’s log files.

Conditions: This problem happens only with command accounting enabled.

Workaround: Disable command accounting. 

CSCed33110

Symptoms: A VIP crash can lead to a memory exhaustion situation on the RSP in turn leading to an 
RSP crash.

Conditions: This will happen more frequently on routers with a high idb count.

Workaround: There is no workaround.
