Error description
We sometimes get a CTL-4 out of UFI9 during CRUISE Verify/Pack . The dump only happens when we are specifying FVN, we have at least 1 find error and we collect statistics. We also have to have a forward chain in the IR record. If we only have a prime IR record then it works.

ABSTRACT OF PROBLEM ___________________ Possible CTL-I000004 dump from UFI9 (statistics update) during CRUISE chainchase. COMMENTS ON PROBLEM ___________________ During chainchase, when CRUISE detects a broken chain it calls UFI9 to update the error count. UFI9 needs the ID and file version of the broken chain to update the correct statistics slot. The current file version is normally set up in EBW039, but when a reference is retrieved it is still set up with the file version of the "from-reference". So, prior to calling UFI9 the "to-reference" file version is set up in EBW039. However, after the statistics update it is never restored to its previous value. So, when a forward chain is retrieved for the "from- reference", the statistics update is done with the incorrect file version which will cause an incorrect entry and possibly a CTL-I000004 dump.
Problem conclusion
SOLUTION ________ In all chainchase monitor segments (UFI3, UFI4, UFI6, UFI7), the current file version (EBW039) is saved before it is modified, and then restored after the statistics update has been done.
