Frequently Queried Log Messages Chapter 4 Using the CSS Logging Features Table 4-8 Cisco 11500 Series CSS Log Messages (continued) Log Message (sys.log: Subsystem Name, Level, and Message) Cause and Resolution ipv4 Subsystem IPV4-4:Ipv4IfMgrCctUpdateMsg: IF config for circuit 1015 not found CIRCUIT-4: Error, Circuit 1015 does not exist. You deleted a circuit but the circuit is still referenced by an ACL or to another configuration parameter. Verify the CSS configuration and make the necessary modifications to remove references to the deleted circuit. IPV4-4: Ipv4ReceivePacket: out of mbufs[, count number, current ingress ce 0x120fa00] An mbuf is a data structure in BSD UNIX-based IP stacks (such as the VxWorks stack) that is used for buffering. This log message indicates the CSS received a packet that was addressed to a CSS IP address, and when attempting to send the packet up the VxWorks IP stack, the CSS had no remaining buffers. These buffers are separate from those used for flow setup and forwarding purposes. They are used only when traffic is sent to the CSS itself, (for example, during a Telnet session). The CSS logs only one message per second that includes the count of how many messages were dropped that second. You can set a flag in debug mode to enable detailed logging (shown in the brackets) of the packet header and ingress logical port of messages dropped during an out of mbufs condition. If you receive this message, contact Cisco Systems TAC. 4-44 Cisco Content Services Switch Administration Guide OL-5647-02
