Resolved Caveats—Cisco IOS Release 12.0(5)
• CSCdm23824
Using any form of RSP turbo switching (optimum/flow/CEF), on any type of Ethernet interface (10
Mb/100 Mb/Gigabit), can cause packet errors in the MAC address fields of packets that are input
from any interface sharing the same MEMD packet free pools as the Ethernet interface.
Workaround: Disable all forms of RSP turbo switching by configuring ip route-cache on all
interfaces, or disable MEMD caching by using either the test rsp cache memd uncached EXEC
command or the memory cache-policy io uncached configuration command.
• CSCdm24099
An array overflow error in the PA-A3 periodic management code might cause memory corruption
on Cisco 7200 series routers. Cisco 7500 series routers do not experience this problem. There is no
workaround.
• CSCdm24281
A Cisco router with Director Response Protocol (DRP) configured might reload with a “spurious
memory access” error. There is no workaround.
• CSCdm24526
A Cisco 6400 node route processor (NRP) will reload when you turn on Interim Local Management
Interface (ILMI) and VC discovery if the Network Service Provider (NSP) configuration includes
the no atm address-registration command.
Workaround: Remove no atm address-registration from the NSP configuration.
• CSCdm25058
When the following message is displayed, a temporary condition exists where the buffers are
completely used and cannot process another event until a buffer is available:
%CSM-1-CAS_MSG_DEPLETED: An error was encountered in enqueuing a CAS message - Msg
headers not available.
There is no workaround.
• CSCdm25601
H.323 inspection in Context-based Access Control (CBAC) might cause a Cisco router to reload.
There is no workaround.
• CSCdm26108
You might be unable to ping your own TR-ISL interface with multiring configured on a Cisco 7507
router if it is connected to a Catalyst 3900 Series Token Ring switch. There is no workaround.
• CSCdm27917
The ds0 busyout command does not survive on a Cisco AS5800 access server if any of the
following occur:
– The access server is reloaded
– The DS3 cable is pulled or replaced
– You issue the shutdown command followed by the no shutdown command on the T1
controller
– The clear controller t1 command is used
There is no workaround.
