BERR704 EXC 0: Bus Error in ISR
SR=0x2708, PC=0x10fa770c, Addr=0xa0010000, SSW=0x105

Can anyone tell me which slot address 0xa0010000 relates to?
 
i want to say that would be a cni address BUT i am not at work. are you getting this often.

Hi Bottylad,

So if you conver the fist HEX code (0x2708) you get TN 036 1 02 16. Is there anything weird going on with that particular user?
 
TelecomGuy, this is a 1000S with small System TN's.

JohnPoole, This is happening on average once or twice per week. The switch WAS cold starting due to COM0008 a few weeks ago so we replaced the Call Server SSC. Now the COM008 have stopped it inhibits BERR704 (followed by cold start!) instead.

Possible faulty (2nd) SSC you think? Not an IP DB? How did you determine the address to be of the SSC?
 
A tip is that you can double-check your patch levels - we had one that was cold-starting and there ended up being a patch on there that was causing the issue - so just be careful especially when newly swapping out SSC's or anything else that needs patches.
 
I've found this below.

How to interpret BERR messages......

Example:
BERR0705 EXC 0: Bus error in Task "tSL1" (0x47f0000)
SR= 0x 3008, PC=0x47b6dac, Addr=0x13326390, SSW=0x070d
SR= Status register. PC=Program counter.

The Addr field here tells us it's a hardware address in Group 3, shelf 0, loop 99.

Because Thor IPB addresses are:
13G (38000-3a7fc) are IGS (where G= Group number)
13G (30000-34ffc) are PS (where G= Group number)
13G (20000-29ffc) are Network loops (where G= Group number)
13G (18038-18ffc) are Clock (where G= Group number)
13G (18020-18ff4) are 3PE (where G= Group number)
13G (0c000-odffc) are MSDL (where G= Group number)
13G (0c000-0c3c0) are SDI,ESDI,DCHI (where G= Group number)

So in the above example the Addr= 13326390 where 133= group 3 and 263= network pack hex 63 =loop 99.

Additionally
IPB space (inter processor bus)
135xxxxx Group 5 Window:
134xxxxx Group 4 Window:
133xxxxx Group 3 Window:
132xxxxx Group 2 Window:
131xxxxx Group 1 Window:
130xxxxx Group 0 Window:
100xxxxx IOP window (Input/output processor)
101b0000 Ethernet SRAM
101a0000 Ethernet Control
10180000 SCSI IOP (from CP)
10170000 RS232
10160000 Data Cartridge
10150000 Prog timer
10200000-1027ffff SRAM
10000000-1001ffff EEPROM

In this case I'm still wondering what a0010000 is for the option 11 systems?


All the best

If it's working, then leave it alone!.
 
Replaced SSC again and updated the deplists and this now appears to be fixed (after a week of monitoring).

I never did find out what address Addr=0xa0010000 referred to specifically!!

Thanks for everyones input.
