   I didn't find any issue with memory. 
   
   I tried increasing the pod memory limits as well as modified the jvmOptions 
to exit on OutOfMemoryError as discussed on slack 
[here](https://apache-pinot.slack.com/archives/C011C9JHN7R/p1696697440481249?thread_ts=1696598440.501329&channel=C011C9JHN7R&message_ts=1696697440.481249)
   
   The error happens exactly one hour after the pod start. I suspect since the 
AWS session token generated by IAM role expires after one hour, Pinot is unable 
to refresh the AWS session token.
   
   So anything related to memory is out of the picture here.
   
   We are currently restarting the pods to run minion tasks. The problem goes 
away exactly for one hour during which our tasks run. After one hour, the 
problem comes back up again and we have to restart the pods again.
