Symptoms

Getting significant application contention on an Update statement which is getting the "SQL*Net break/reset to client" wait.

This causes significant impact when 100 of these sessions are getting this wait. Also, it seems that very few records are actually updated and in some cases none.

This is impacting the overall performance on a production DB server.
