Where can I get more info on the following error:
May 4 18:11:11: %C4K_IPROUTEMAN-3-FIBADJMANDUPLICATEADJ: FIB Entry: Tried to create a duplicate adj for key 192.218.223.76/20
May 4 18:11:11: %C4K_IOSIPROUTEMAN-3-ADJMANNOMOREADJS: AdjMan: hardware adjacency resources exhausted, performance may be degraded.
The ip address (altered) in question would belong to a dhcp client that would be plugged into an edge switch (2950xl) and not the core switch. An odd item of note: the dhcp assignment would have a 24 bit netmask, not the /20 as indicated above.
Given the nature of our network, the end users are conference visitors/exibitors that are only connected to the network during a conference and leave once the show is over, so I cannot access the offending end device to examine it.
The last time I saw this error was during a conference that had a lot of Mac users.
Thanks
