patch 20953340 fails at wfidxc2.sql after 3 hours

Hi:

I'm applying CPU patch 20953340 and it fails after hanging while running wfidxc2.sql. Looking at the logs, the reported error appears as INDEX tablespace not having enough space, but the fact is that there are over 10GB of free space.

TABLESPACE_NAME

MAXTOTAL

USED

FREE

PCT P   PCT_REAL

------------------------------ ---------- ---------- ---------- ---------- - ----------

APPS_TS_TX_IDX

545062912  534798848   10264064 98.1169029 * 98.1169029

Do you guys have any idea as to why it takes so long and then fails and how to get around this? Or should I raise an SR?

I'm also attaching the patch's logs.

Thanks and cheers,

Alfonso
