In our office environment few servers mostly  database servers and yesterday it
for one application server(first time) the partion is getting "read only".

I was checking the archives, found may be similar kind of issues in the
2007-July archives. 
But how it has been solved if someone describes me that will be really helpful.

In our case, just at the problem started found the line in log file as follows:

     EXT3-fs error (device dm-12): edxt3_find_entry: reading directory #2015496
offset 2

Then one blank line
Then the line is

    Aborting journal on device dm-12.
    ext3_abort called

    Ext3-fs error (device dm-12): ext3_journal_start_sb: Detected aborted
    Remounting filesysem read-only

Then the continuous line as follows:

    EXT3-fs error (device dm-12) in start_transaction: Journal has aborted

The above message is continuous  until we remount the filesystem and partion

We could not figure it out what is the root cause of the system.

We are using individual EMC luns and are configured with LVM volume groups and
then mounted on logical

Here i am giving the server description:
