Yes, we have the same on IDS7.31
seems to be normal, overrun of some internal profile counters.
So you have to reset the counters once week or so : onstat -z

Subject: Cached reads going to 0.00% [6973]
I've noticed this a couple of times in onstat, for no apparent reason cached
reads go from 95% or so to 0.00% and then slowly build back up to 95% over
the
next 24hours or so. There's a cronjob that runs at 8, noon, 5 and midnight
that records a few interesting statistics on the machine. We're running
Informix 7.31.UD6 upgrading to a 9.4 on HPUX 11i. The hardware is a little
old
and we have had problems with disk failures in the recent past, any clues?
