OL-10394-05 Rev. R0
Conditions: Under certain crypto configurations with NetFlow also configured, the router will
reload when required to fragment CEF-switched traffic on a Cisco 7200 router.
Workaround: There is no workaround.
CSCsu32104
Symptoms: A PRE-3 that is running Cisco IOS Release 12.2(31)SB code may encounter a Redzone
overrun memory corruption crash.
Conditions: Unknown at this time.
Workaround: Turn off Auto IP SLA MPLS by entering the auto ip sla mpls reset command.
CSCsu35597
Symptoms: Renaming a directory gives error message.
Conditions: This happens on a Cisco router running Cisco IOS Release 12.4(20)T1.fc2 image
Workaround: There is no workaround.
CSCsu35624
Symptoms: When a private VLAN is configured on a VTPv3 server and then deleted, the update
message on a peer VTPv3 client can cause a stack overflow for VLAN manager process and crash.
Conditions: Occurs in a Cisco 7600 running Cisco IOS Release 12.2(33)SRD.
Workaround: There is no workaround.
CSCsu36697
Symptoms: The line card reloads when a line card online insertion and removal (OIR) is performed.
It does not happen consistently.
Conditions: This occurs when an empty policy is present.
Workaround: There is no workaround.
CSCsu36709
Symptoms: A router may unexpectedly reload.
Conditions: The symptom is observed specifically with a configuration of Enhanced Interior
Gateway Routing Protocol (EIGRP) that is used to redistribute BGP routes. Plain EIGRP is not
affected.
Workaround: Do not use EIGRP to redistribute BGP.
CSCsu36836
Symptoms: TCL scripts and policies attempting to work with open files and sockets simultaneously
may not operate properly. One symptom is the vwait command may fail by reporting “would wait
forever”.
Conditions: Occurs when a TCL script opens both a file and a client or server socket simultaneously.
Workaround: Open and close files and sockets separately. Avoid having them open simultaneously.
CSCsu37205
Symptoms: BGP dampening under VPNv4 may cause router crash.
Conditions: Occurs when BGP dampening is enabled on VPNv4 address family, but not on
individual IPv4 VRF<VRF-name>address-family.
Workaround: Enable the same set of BGP dampening on both the VPNv4 address family as well as
all entries for IPv4 VRF address-family.
