Deadlock issues: revisited

Not to long ago, there was a thread re: DSA aborting transactions due to possible deadlock detection. I have not been able to find any of my mail regarding this, and hope that someone might be able to provide a summary of this discussion. I am experiencing deadlock problems, when trying to run multiple instances of the same application. Something just doesn't feel right, and before getting out the flame-thrower, I'd like review the earlier discussion. If anyone could provide me with a summary, or direct me to someone who could enlighten me, I'd be very appreciative. Jon Vemo
