Error
In sm.alert.log this line is logged when this happens.
RTE I Corruption-3-ir.probsummary, Corrupted IR index detected ; user(bob.Bob), application(cc.search), panel(select)
Cause
The error in the sm.alert.log indicates that IR Regen will help. However, when service manager configuration has 1, 3 or more instances the IR regen fails.
STR:
1. Setup HZ scaling with 1 or 3 nodes.
2. Go to the scirexpert file and purge all the data.
3. Go to any dbdict with an ir key and perform a ir regen.
4. Go review the scirexpert file. You will get a no data found.
5. Note that if you run the same tests with 2 nodes(instances) the ir files are rebuilt correctly. This was tested with 4 nodes(instances) to see if it was an issue with even vs odd number of nodes. The ir files were not rebuilt with 4 nodes either.
Nothing is written to the log indicating an error even with irtrace parameters in the sm.ini file
