Hi @anton-epsagon,
What makes you think it’s an Out of memory error?
From your log I find the following error:
Connection org.postgresql.jdbc.PgConnection@1280851e marked as broken because of SQLSTATE(08006), ErrorCode(0)
I think the connection to your source database was lost after 3 hours.
Could you please check to what extent your source database is under heavy load while Airbyte is consuming its data? A lack of resources on the source database might be the reason of a connection reset.
Could you also try to tweak the JDBC URL params to customize timeouts? Such as socketTimeout=600&options=-c%20statement_timeout=5min
The list of available JDBC params is available here.
