Geoffrey -
We had a similiar problem... But it was with 7.13. It sounds as though it
is still lurking around!
Our case number was 681114. Also, the following may help in dealing with
Tech support...
it is what we received from Informix Tech Support ( what does the engine do
once a restore is
done??? "Fast Recovery" :
Bug: 72823 FAST RECOVERY LEAVES TWO LOGICAL LOGS MARKED AS CURRENT IF
THE MOST
RECENT CHECKPOINT RECORD IS FOLLOWED IMMEDIATELY BY PG_LOGEND PAGE
Prob: 67802

Subject: Two logical logs marked as Current ?
Has anyone seen such a problem before - 2 logs marked as 'C' i.e. current ?
See the bottom of the email for the online.log. This all resulted in a full
system restore, Informix Tech Support didn't give an information and were
very defensive about bugs in the server ? All attempts to free up the
logical logs failed. I would appreciate an insight anyone has to offer -
without an identification of what happened who knows whether it will happen
again !
