Dunno yet, but I think so.

        Errors in file
        ORA-01171: datafile 12 going offline due to error advancing
        ORA-01110: data file 12:
...                              Is this ext3 ?

Yes, this is ext3.

        ORA-01115: IO error reading block from file 12 (block # 1)
        ORA-27072: skgfdisp: I/O error
        Linux-x86_64 Error: 5: Input/output error

... are there corresponding /var/log/messages entries for these EIO
errors tht would impugn the scsi layer or other goodies downwind? Trying
to establish if this is an EIO pushed up from a software layer (perhaps
powerpath) ?   Being intermittant there whould be /var/log/messages
goodies to clue us in

No IO error messages that I can find yet, but did find something else:

There are 2 other databases running the same app, same versions of Oracle, so it
is a little difficult to be sure which is causing the problem.

Since most of these are the past 2 days, it could be that this is just a symptom.  The IO errors
may have crashed ctxhx (I'm assuming it has something to do with building Text indexes)
