we currently have a problem with PI ICU on different OPC interface nodes. For unknown reason, ICU crashes most of the time when we try to go to "Health Points" screen.
They also crash when we do a Tools -> Diagnotics. The ICUDiags file stops at the very first line of "Entire IORates.dat file:"
The crash occurs ~80% of the time. It's intermittent.
Int OPC DA versions are 18.104.22.168 or 22.214.171.124. We have tried installing OPC DA plug-ins 126.96.36.199 with no success solving the problem.
We have a few nodes that have no problem at all, but no clue why. Nodes running 188.8.131.52 work like a charm.
Servers are Windows server 2008 or 2012.
Here is an example of ICU crash:
