Symptoms: L3 communication with the router through the VLAN interface (SVI) for non-default
VLAN may break. For example, pings from VLAN interface to any device connected to
switch-port/s in that VLAN, may not go through. If the show mac-address-table executive mode
command is executed, entry marked as "Self" will not be seen for the non-default VLAN SVI (It
would be seen only for VLAN1 SVI).

Release 12.3(11)T6. The gateway is under heavy voice call load with access to media/application
documents residing on local gateway flash, http and tftp servers.
Workaround: The following is not quite a workaround:
call threshold global cpu-5sec low value high value
For example:
call threshold global cpu-5sec low 50 high 70
The CLI can ease the CPU load on the gateway by reducing the probability for a crash.
