Dear all,
Today I faced two bus errors on my cisco 2911 router. Of course, after it occurs, router rebooted. Below is a detailed information about second one:
System returned to ROM by bus error at PC 0x23B1DEEC, address 0x3C at 09:06:47 UTC Tue Apr 9 2013
System image file is "flash0:c2900-universalk9-mz.SPA.152-3.T.bin"Last reload type: Normal ReloadLast reload reason: bus error at PC 0x23B1DEEC, address 0x3C
Stack trace from system failure:

Just before bus error, I had following error message in console:
*Apr 9 09:06:44.611: %SYS-2-NOBLOCK: may_suspend with blocking disabled. -Process= "Ethernet Msec Timer CFM", ipl= 0, pid= 119
-Traceback= 23C7D6F8z 21296A50z 23C3A8E8z 23C3A8CCz
*Apr 9 09:06:44.631: %IP_VFR-4-FRAG_TABLE_OVERFLOW: GigabitEthernet0/1: the fragment table has reached its maximum threshold 16
*Apr 9 09:06:45.623: %SYS-2-BLOCKHUNG: Task hung with blocking disabled, value = 0x1. -Process= "Ethernet Msec Timer CFM", ipl= 0, pid= 119
I will add, that I had IPSLA configured on ga0/1 and ga0/2 , on ga0/0 I have NAT.
I suspect bad IPSLA configuration, but I a, walking in the fog right now.
Thank you in advance for any help, tip or support.
Regards
Piotr
