ERROR: EXCEPTION_ACCESS_VIOLATION when multiple task read from LOG STREAM

Hi,

we are getting this error randomly as a global error, it happens today (28/08) and 22/08. When we get this error all the task went down with the following error

Failed to receive: An existing connection was forcibly closed by the remote host.

In our case we have a LOG STREAM main task, that read insert/update and delete from ORACLE, and other task that read from it.

Hi @pontisa

An access violation could indicate that something was holding a lock on a file when we tried to access it. Please exclude the Replicate binary file location, data folder location and log stream file locations from anti-virus monitoring.

I'm not sure the communication error is directly related. It appears either the source or target disconnected from the task, or a firewall/router/switch between them forced it closed.
