Sorry I think the description is not so clear:

panic_thread:
panic_thread: 2a10004fcc0
> address$<2a10004fcc0 ----> Change it to
2a10004fcc0$<thread

Change this please
Best regards
joerg

thanks it work out ..but after that this comes up ...how to understand this ... 2a10004fcc0$<thread

How will i diagonse the problem which made the server rebooted...from the above result..

OK thats perfect!

And now this please:

0x2a100057cc0$<proc2u


And send me the output!

Best regards
joerg

> 2a10004fcc0$<proc2u
{
mdb: failed to read u_execsw pointer at 2a100050100: no mapping for address
}
>
this is what come if I type in address<proc2u what might be the issue ..

I'm confused!
OK pleas provide me the output of this command:

2a100047cc0$<proc2u

Important is that you do the commands all in serial order.

Short explanation:
This localize the panic thread:
> panic_thread/K
panic_thread:
panic_thread: 2a10004fcc0

This is the pointer to the memory where the thread is:

2a10004fcc0$<thread


And inside the output we are looking for the procp Pointer this is a pointer to the proc structure so we can identify the command or program with cause the panic.

The problem for me is that SUN changed the format of the output to XML.
In the moment I have no core files to test is on the lab.

.....
t_procp = p0
t_audit_data = 0
t_next = 0x2a100047cc0
t_prev = 0x2a100057cc0
t_whystop = 0
.....

And this was (I hope my!) mistake:
2a10004fcc0$<proc2u
change it to :
2a100047cc0$<proc2u
and try this additionally
2a100057cc0$<proc2u

Please try it and inform me!

Best regards joerg

hey , tht cmd is not mapping
2a100047cc0$<proc2u

this provide output like this..

> 2a100047cc0$<proc2u
{
mdb: failed to read u_execsw pointer at 2a100048100: no mapping for address
}
> 2a100057cc0$<proc2u
{
mdb: failed to read u_execsw pointer at 2a100058100: no mapping for address
}


it says failed to read ..is tht mean there is no process running at tht time ..

Sorry for the delay.

After a long search I find 5 files to test, but only with one I was able to test my old learned procedure with succses.

So at this point you need someone with more knowledge about this topic.

Sorry!!
