• CSCed62835
Symptoms: A Cisco platform may crash after the following error is seen:
SCHED: Stack for process CEF IPC Background running low, 48/6000 %SYS-SP-6-STACKLOW:
Stack for process CEF IPC Background running low, 48/6000
Conditions: This symptom is observed with a recursive prefix with multiple next hops when these
next hops match host routes that themselves are recursive prefixes and recurse through themselves.
Workaround: Avoid recursion loops.
• CSCed63357
This caveat consists, of six separate symptoms, conditions, and workaround, of which the first three
apply to all Cisco IOS releases and the last three apply only to Cisco IOS Release 12.3 T:
1) Symptoms: There are three symptoms:
– There may be a inconsistent or duplicate display of files between the show diskslot-number and
dir diskslot-number commands.
– When a file is deleted from the CLI, the file may be deleted but a “No such file” message may
be printed.
– One cluster may leak. Entering the fsck command truncates the original file and creates an
orphan file for the leaked cluster.
Conditions: This symptom is observed when an application creates or opens a file without the
“O_TRUNC:” mode, as in the following example:
show version | append disk#:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#vtp file new
Setting device to store VLAN database at filename new.
Router(config)#^Z
Workaround: There is no workaround.
2) Symptoms: The show diskslot-number and dir diskslot-number commands may show
inconsistent information (such as inconsistent file sizes) when multiple images are copied.
Conditions: This symptom is observed when you make two copies of the image file to the disk by
using two vtys and by entering the dir diskslot-number command at the same time.
Workaround: Do not enter the show diskslot-number and dir diskslot-number commands when
multiple images are being copied.
3) Symptoms: There are two symptoms:
– The show diskslot-number and dir diskslot-number commands may show inconsistent
information.
– Entering the fsck command may delete or truncate the valid files or create an orphan file for an
unused cluster.
Conditions: This symptom is observed when you rename a directory that consists of many
subdirectories or files.
Workaround: Reload the router.
