Omar,
I don't know the exact details/science, but you could rid yourself of fuzzycheckpoints by just turning them off. Your regular checkpoints will still happen, just not the fuzzy's. In the environment of the user that starts informix, set NOFUZZYCKPT to 1, then stop/start Informix. We were IDS 9.4 (64bit) on Solaris 9. We were running SAP, not that it matters, but were advised by SAP to turn off the fuzzy's.

I think is unlikely that the problem is related to the fact this is a
"fuzzy" checkpoint. If you don't see that the prolem is I/O, maybe th
eproblem is that a thread is in critical section (look in onstat -u for
a thread with the "X" flag). Then try to analyze what is this thread doing.
