Trace the process that is hanging. It most likely has nothing to do with SGA size or open_cursors.
hmmm...i wud have loved tracing but how am i to know which session will block others until it really blocks others..N if i start tracing after it blocks others, I am not likely to get the statement that really caused locking...Isn't it?

It is only blocking other sessions and the problem corrects after 10-15 minutes....So how comes deadlock..
