    Dead Lock Issue

    I am running into a dead lock issue almost once everyday for the past one month. There is a process which is creating this deadlock issue on the database. I am not able to identify and resolve it. COuld someone tell me how to go about idetifying this partucluar process which is causing the dead lock ? It is the exact same trace file which is generated with every dead lock. Also even tho I have a huge Temp tablespace and have increased the sort area by double I am getting cannot increase temp segment by xxxx right after the dead lock.

    I am also pasting/attaching the trace file to this thread. ANy help will be appreciated.
