Timeout exceptions during snapshot generation
There is a problem with the Adaptive Decision Manager (ADM) data mart agent that captures information about the state of models, predictors, and predictor binning.
The adaptive models in your system are large, or the Pega Platform server is busy.
Expand the SysAdmin category, and then click Dynamic System Settings.
Decrease the admmart/batchSize dynamic system setting from 50 to a lower value, and save the change.
