Comment 1 Eric Sandeen 2008-04-21 14:37:42 UTC

What does syncing have to do with this problem?

Is this during system shutdown?

Were there other error messages that you did not include?

Can you reproduce this?

What modules are loaded at the time?

What sort of swap setup do you have?

Comment 2 Keerthi Prashanth S. 2008-04-22 02:04:43 UTC

Hi Eric,
No this is not during the shutdown process..When an application is run in this
the machine then this error is thrown..Afterwards we have to reboot the machine....

Comment 3 Eric Sandeen 2008-04-22 02:12:57 UTC

Can you answer any of the other questions, please, to provide more info on the
problem?

Comment 4 Keerthi Prashanth S. 2008-04-23 02:31:52 UTC

Hi Eric,
what else u want? Could u please let me know?

Comment 5 Eric Sandeen 2008-04-23 02:50:55 UTC

Hi, there were several questions in comment #1... just trying to get a picture
of what might be going on.  If you can provide the requested info it might help.

Thanks,
-Eric

Comment 6 Keerthi Prashanth S. 2008-04-24 03:40:05 UTC

Hi Eric,
As per the previous comment#2  the error occurs when the machine is running some
applications...

Actually the error messages what it throws is pasted here as u can see above..
 
Right now cannot..but when it happens next time i can..

Comment 7 Eric Sandeen 2008-04-24 03:46:47 UTC

So, the remaining unanswered questions are, just to be clear:

What does syncing have to do with this problem?

Were there other error messages that you did not include?
(I see that you pasted errors; the question I had was, were there other errors
that you did not paste, did you possibly edit out anything that is interesting...)

Can you reproduce this?  i.e., does this happen more than once.

What modules are loaded at the time?  (lsmod will tell you)

What sort of swap setup do you have?  swapfiles?  devices?  how many?  how big?

Comment 8 Eric Sandeen 2008-08-23 04:39:26 UTC

Without the requested info I cannot make progress on this.
