Frequently Queried Log Messages
Cause and Resolution
In the case of software queues, it might
be possible for some task on the MIPS
processor to deplete the MCID pool by
sending a large number of messages to
a group that contains both local and
remote members. If the local member
has a very large queue, the queue could
fill up before running the recipient
task, processing the messages, and
freeing the buffers.
Of the two potential causes, the most
likely causes is the CSS receiving a
large number of packets which it must
flood out all ports.
This log message typically occurs
when the CSS loses a specific route
and forwards the flow out the default
gateway. The default gateway then
forwards the flow back to the CSS
because the routing table lists the CSS
as the next hop. As a result, the packet
is continuously routed out the default
gateway and back to the CSS.
