Problem with deletes in ESQL/C in Ver. 7.14

We upgraded from 7.12 to 7.14 this past weekend. Ever since we have been experiencing trouble that takes the server down. So far it has been difficult to diagnose when, where, and why. However, we have narrowed it down to it appears to be a problem with deletes within a C app that we run daily. We have cascading deletes on several tables. By using various debugging methods we have captured stack traces and log messages following the crash of this program. These messages have often indicated difficulty while deleting. I am sorry I don't have the traces available at this time. Does this sound familiar to anyone?
