Resolved Caveats—Cisco IOS Release 12.0(4)
• CSCdk86081
The downstream physical unit (DSPU) does not allow any new DSPU connections, and the
following messages appear in the router log:
%DSPU-3-LSConnInFailedNoMem: Connect in from remote address 00104b0a60e0 failed ;
insufficient memory %DSPU-3-LSConnInFailedNoMem: Connect in from remote address
00105a00e326 failed ; insufficient memory
There is no workaround.
• CSCdk89189
A Cisco 2600 series router that runs DLSw with priority and backup peers over BRI might reload
with SegV exception.
Workaround: Do not have priority peer configuration.
• CSCdk90257
A second link fails to reactivate during recovery. Both links must be restarted in sequence so the
links will activate the first link as transmission group 21 (TG21) and second link as TG22.
Otherwise, the failing link stays in TG0 state, attempting to reconnect.
Workaround: Assign specific TG numbers (from 1 to 20) to parallel TGs.
• CSCdk93916
An Advanced Peer-to-Peer Networking (APPN) router might reload with the following backtrace
message:
0xRA:0x60757578:Qdeq(0x6075756c)+0xc 0xRA:0x606FBA6C:hs_deleter(0x606fb930)+0x13c
0xRA:0x606FC038:mu_processor(0x606fbe40)+0x1f8
0xRA:0x606FC77C:remote_path_control(0x606fc650)+0x12c
0xRA:0x606FDC04:pc_mainline(0x606fd500)+0x704
0xRA:0x606F8D70:xxxpcasm(0x606f89d0)+0x3a0
There is no workaround.
• CSCdm00997
APPN Berkeley Internet Name Domains (BINDs) from low entry networking (LEN) nodes, such
as MS SNA-Server, might fail in a pending active state when the router is also an intermediate node.
The BIND transmission header (TH) is corrupt in the forwarded direction, which is then typically
dropped by the receiving device. There is no workaround.
• CSCdm02196
A Cisco 7206 router might reload with a bus error with the following message:
System restarted by bus error at PC 0x6087AD40, address 0x244
This only happens directly after the router is reloaded. After the router is up and running the system
is stable. There is no workaround.
• CSCdm05337
An APPN router might reload with the following stacktrace:
RA: 0x601C89D4[abort(0x601c89cc)+0x8] RA: 0x601C7354[crashdump(0x601c728c)+0xc8] RA:
0x607375F0[Eattach(0x60737588)+0x68] RA: 0x60739DCC[Pcreate(0x60739cd4)+0xf8] RA:
0x60648720[amp610(0x606486c0)+0x60] RA: 0x6064789C[amp500(0x60647510)+0x38c] RA:
0x60645AD0[amp00(0x60645790)+0x340]
In this situation, the router uses excessive processor memory when multiple ENs (over 100) register
resources to this NN at the same time. There is no workaround.
