- Earle,
-
- You have left out a few details, but I would think about recompiling and
- relinking these executables under the new version of VMS 5.4. Thats a
- pretty big jump 4.7 to 5.4. VMS version 5, is a major upgrade over version 4.
- Unless of course the recompiling was done as part of the upgrade process.
-
- It is strongly suggested that applications be recompiled and relinked as
- part of a major operating system upgrade. You indicate the problems started
- after the recent upgrade, I would start there.
-
- Your DEC support folks should be able to analyze your crash dumps and advise
- as well.
-
- Good Luck,
-
- Steve
