Caveats
Resolved Caveats—Cisco IOS Release 12.0(30)S
• CSCef15418
Symptoms: A router cannot write to Bootflash.
Conditions: This symptom is observed on a Cisco router after you have entered the squeeze
bootflash command.
Workaround: There is no workaround.
• CSCef53395
Symptoms: A memory leak may occur in the IPC buffers of a Cisco router, and the output of the
show processes memory command shows that the Pool Manager process holds increasingly more
memory.

5 0 149227592 69514888 79894996 135335724 66834832 Pool Manager
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS
Release 12.0(26)S2 or 12.0(26)S3. The memory leak is triggered by the SNMP polling of specific
OIDs within the ciscoEnhancedMemPoolMIB MIB.
Workaround: Prevent the ciscoEnhancedMemPoolMIB MIB from being polled by explicitly
configuring an SNMP view. To prevent this MIB from being accessed via any community strings,
create a view and apply the view to all communities configured, as in the following example:
snmp-server view NOMEMPOOL iso included
snmp-server view NOMEMPOOL ciscoEnhancedMemPoolMIB excluded
snmp-server community public1 view NOMEMPOOL ro 6
snmp-server community public2 view NOMEMPOOL ro 7
snmp-server community public3 view NOMEMPOOL ro 8
The specific MIB that is being blocked is ciscoEnhancedMemPoolMIB (1.3.6.1.4.1.9.9.221).
Once the configuration is in place, the router must be reloaded to clear the IPC cache and free the
memory.
• CSCin63066
Symptoms: When a new probe (for example, index $PROBE_ID) is created through SNMP, the
probes that have index numbers that are greater than $PROBE_ID are not shown in the output of the
show rtr configuration and show rtr operation-state commands.
Conditions: This symptom is observed when the probe is created in the CREATE_AND_WAIT state
by entering the following command:
unix_xterm>
setany -v1 $ROUTERIP public
rttMonCtrlAdminStatus.$PROBE_ID 5
In addition, there is no subsequent SNMP configuration command for the probe.
Workaround: Enter a subsequent SNMP configuration command to make the probe configuration
complete, as in the following example:
setany -v1 $ROUTERIP public \
rttMonCtrlAdminRttType.$PROBE_ID -i 1 \
rttMonEchoAdminProtocol.$PROBE_ID -i 2 \
rttMonEchoAdminTargetAddress.$PROBE_ID -o "05 00 00 02"
