Basic System Services
• CSCea21328
Symptoms: After a Versatile Interface Processor (VIP) has reloaded, there does not seem to be a
crashinfo file because the crashinfo file is not closed; therefore, it is not visible or accessible. If the
same VIP reloads again, both the first and second crashinfo files are accessible.
Conditions: This symptom is observed on a Cisco 7500 series that is running Cisco IOS
Release 12.2(6f). The symptom may also occur in other releases.
Workaround: There is no workaround.
• CSCeb20967

Symptoms: A Route Switch Processor (RSP) may reload unexpectedly when a bus error with an
invalid memory address occurs while packets are placed into a hold queue.
Conditions: This symptom is observed on a Cisco 7500 series that runs Cisco IOS Release 12.0 S,
12.1(14)E4, or 12.2 S when the following sequence of events occurs:
1. A packet is switched via Cisco Express Forwarding (CEF).
2. The egress interface has queueing/shaping configured.
3. The egress interface is congested, causing the packet to be placed into the hold queue.
Workaround: There is no workaround.
• CSCec39376
Symptoms: A Flash memory card may become corrupted. The output of the show flash-filesystem
EXEC command may display the following information:
Open device slot0 failed (Bad device info block)
Conditions: This symptom is observed on a Cisco platform when you perform an online insertion
and removal (OIR) of the Flash memory card.
Workaround: Do not perform an OIR of the Flash memory card. Rather, switch off the router and
perform an offline insertion and removal.
If the Flash memory card does become corrupted after an OIR, reformat the Flash memory card.
• CSCec69536
Symptoms: When you reload a Cisco 7500 series router with a new Cisco IOS software image, the
router may reload unexpectedly during the bootup process and generate an “Imprecise cache parity
error” message.
Conditions: This symptom is observed on a Cisco 7500 series that is configured with a Route Switch
Processor 8 (RSP8) and that runs Cisco IOS Release 12.0 S or Release 12.2(18)S when you reload
the router with an image of Cisco IOS Release 12.3 T.
Workaround: Do not reload the router. Rather, power-cycle the router to properly load the image of
Cisco IOS Release 12.3 T.
