Odoo 14 Serialization and Postgresql issues

Job ID: 36810637

Budget: $20 – $40 USD

We have an issue with a Odoo 14 community POS that has multiple POS sessions open and we get high load on the server and these errors in the logs:

psycopg2.errors.SerializationFailure: could not serialize access due to concurrent update

We need someone who is familiar with these issues who can identify the issue and provide a solution/fix.
