Hi Chris
We have seen this. It seems to corrupt an r file when packing that r file. So
if for you an r file holds about 18 hours of data this maybe the reason.
We run the following to fix it.
cd /opt/aim/bin
xrebuild instance 0 (where instance is your historian instance)
xrebuild is documented in the Aim* manual.

All knowing List--
I have had a couple of instances recently where trending was being viewed in
the morning but then in the afternoon when attempting to look at more trending
everything was flat lined for ~18 hours. Before and after the 18 hour span we
have good data. I suspect that the data file might be corrupted or didn't save
properly . Has anyone else seen this? Is there a fix. We use the historian
and report package to compile data for MON/MACT reports. When we don't have
the data due to an instance like this we have to report to the EPA.
Thanks in Advance,
Chris
