Thanks for the link. The example shown at the bottom of the article looks like an unindexed foreign key issue rather than an initrans/pctfree issue. What's really strange about my deadlock is that it shows no other session waiting on the lock except itself.
Originally, I thought the deadlock we were encountering was a lack of ITL slots based on all the articles I had read at the time but when I attempt to reproduce the ITL shortage scenario I always get what looks like a traditional deadlock (X waiting for X) when I deliberately deprive a block of ITL slots. I'm open to ideas, suggestions...
