Environment

Release: Any
Component: OI_CONNECTOR

Resolution

Startup memory for the probe was set to:

options = -Xms512m -Xmx2g -Duser.language=en -Duser.country=US

we changed this to:

options = -Xms512m -Xmx6g -Duser.language=en -Duser.country=US

now reconciliation is working.

Depending on the environment this may need to be increased even more. This is a starting point.
