Description

Hi Team,

There is high memory usage during the APIM Analytics server restart. During the investigation, we found that this issue occurs because the analytics server tries to recreate the state even though there are no issues with the aggregation. We identified a possible root cause at the code level, and we need to fix it.

Steps to Reproduce

This issue reproduces when there is a large amount of data for aggregation. The Analytics server tries to load the AGG_TIMESTAMPS of each granularity and recreate them during the restart, even though there are no issues. If there is a high volume of data, it leads to an Out Of Memory (OOM) state.
