We are trying to upgrade to ACS 7.1 with AWS Postgres 13.5. After Upgrading Postgres from 11.9 to 13.5, ACS Pods do not come up. We have upgraded our lower environments i.e. Development and Staging to ACS 7.1 with Postgres 13.5 and have no issues. This issue of the ACS 7.1 pods not coming up only exist in the performance and production environment.
The only difference I see is the data where in the lower environments, we do not have much data in the perf and prod environments we have over 100M+ documents. If someone has faced this issue, please advise and what was the solution.
This is very environment specific case, can you trace any failure logs. Can you check all containrs crash or just acs container crashes? Did you also updated the jdbc jar matching to the latest version of pgsql ? Likely be some config issue or memory issues.
