Symptoms: A router may crash spontaneously and display the following message:
%SYS-6-STACKLOW: Stack for process RIP Send running low, 0/6000
Conditions: The symptom is observed on a router that is running Cisco IOS Release 12.2SB. RIP
packets that go through many features in this environment (such as, RIP -> IP -> MLP -> PPP ->
L2TP -> IP -> QoS/HQF -> driver) may also cause the stack overflow.

Symptoms: The interface output rate (214 Mb/s) is greater than the interface line rate (155 Mb/s).
Conditions: This symptom is observed with a Cisco 7600/7500/7200-NPE400 and below. That is,
PA-POS-2OC3/1OC3 (PULL mode).
PA-POS-2OC3/1OC3 (PULL mode).
Workaround: There is no workaround.
Further Problem Description: From the Ixia, packets are transmitted at 320 Mb/s. On the UUT
(Cisco 7600), the outgoing interface (POS-Enhanced Flexwan) shows the output rate as 200 Mb/s.
But the interface bandwidth is 155 Mb/s.

Symptoms: With bidirectional multicast traffic, a router that is running Cisco IOS
Releases 12.2(33)SB, 12.2(31)SB3, 12.2(28)SB7, or later versions may stop forwarding all traffic,
or even crash. Ping/ARP fails from adjacent routers as all packets are dropped.

or even crash. Ping/ARP fails from adjacent routers as all packets are dropped.
Conditions: This symptom occurs when any event that causes multicast adjacency to be removed
(temporarily) from PXF, causing packets to be punted to RP. Some examples are:
