Caveats for Cisco IOS Release 12.2(33)SRD through 12.2(33)SRD8
OL-10394-05 Rev. R0
• CSCsg99677
Symptoms: Crashinfo collection to a disk filesystem will fail and generate the following error
message:
File disk#:crashinfo_20070418-172833-UTC open failed (-1): Directory entries are
corrupted, please format the disk
Or the crashinfo file will be stored as CRASHI~1.
Conditions: This symptom is observed with normal crashinfo collection to a disk filesystem.
Workaround: Configure the crashinfo collection either to a network filesystem (such as tftp or ftp)
or to a local filesystem of type “flash”. Configuring to a local filesystem is a preferable option.
• CSCsk48102
Symptoms: Supervisor crashes due to an address error on the switch processor:
Address Error (load or instruction fetch) exception, CPU signal 10
Conditions: This appears to be a very rare random occurrence that only occurs in devices that have
uptime over one year. In some cases, the devices were up for over two years before encountering
this.
Workaround: There is no workaround.
• CSCsm97014
Symptoms: MLPoFR with the member group interface as crackerjack PA (PA-MC-2T3-EC) is
configured. On applying a simple policy along with RTP header compression virtual template, the
connectivity breaks.
Conditions: This is seen across PA (PA-MC-2T3-EC) and on applying both header compression and
QoS policy.
Workaround: There is no workaround.
• CSCso50205
Symptoms: If a SSM static mapping command is used and router processes SSM groups outside the
configured static SSM mapping range, routers fall to DNS-based look to find SSM mapping. If DNS
servers are not reachable or DNS servers are not configured to provide mapping, input interface Q
builds up leading to control plane instabilities affecting other protocols.
Conditions: This symptom occurs when DNS-based SSM mapping and DNS servers are not
reachable.
Workaround: If SSM mapping information is never fetched from a DNS server, configure no ip
igmp ssm-map query dns.
If DNS is used, ensure that DNS servers are always reachable and also have low DNS query timeout
value.
• CSCso60442
Symptoms: A crash occurs.
Conditions: This symptom is observed when the show buffers interface dump command is entered.
Workaround: There is no workaround.
• CSCsr39340
Symptoms: Packets may be dropped.
Conditions: This symptom is observed if the core interface for AToM is a GRE tunnel.
Workaround: There is no workaround.
