Here's a hilarious example. It doesn't take much. No complex config
required. Just a Cat5k RSM, 12.0(7)T Enterprise/IPSEC/FW IOS, and even a
blank config to start! See below:
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int vlan 1
Router(config-if)#ip address 1.1.1.1 255.255.255.0
Router(config-if)#no shut
Router(config-if)#exit
Router(config)#
14:21:36: %LINK-3-UPDOWN: Interface Vlan1, changed state to up
14:21:37: %LINEPROTO-5-UPDOWN: Line protocol on Interface Vlan1, changed
state to up
Router(config)#router bgp 1
Router(config-router)#
Router(config-router)#network 1.1.1.0
Router(config-router)#^Z
Router#
14:21:58: %SYS-5-CONFIG_I: Configured from console by console
Router#sh run
Router#
14:22:05: %SYS-2-MALLOCFAIL: Memory allocation of 126968 bytes failed from
0x60207038, pool Processor, alignment 0
-Process= "Exec", ipl= 0, pid= 69

6027BF84 6027BF70
Router#sh run
Router#sh run
Router#
The router will then reboot itself. If you didn't get a chance to save the
config, you come up with a fresh start. If you think you're smart, like I
did, and do a quick write to memory, the router will reboot itself
continuously...
My solution was to downgrade to 12.0(5)T same featureset. I suppose I should
go to 12.1.something...
