Trying to troubleshoot a stuck program. The program gets stuck at a particular wait event 1 out of every 8 runs on an average. When the program completes, it finishes in few minutes. When it is stuck, the P1, P2 values are always the same. Can you please tell what the P1, P2, P3 values represent.

Current Wait Event enq: IV - contention

Current Wait Class Other

P1                         type|mode 1230372869

P2                         id1 1398361667

P3                         id2 3

Object                   None

They are not OBJECT_IDs.

Thanks for your help.
