One of my replicated VM's is not replicating to ASR anymore.

Below is the screen grab of the full error.


I've followed the troubleshooting steps to no avail.

Wondering if someone could point me in the right direction.

    @Artur Gawrych Thank you for reaching out to us!

    I see that you mentioned that one of your replicated VM's is not replicating to ASR.

    This error code means that there are too much data stuck at the process server(PS), it cannot be sent to the site recovery in a short moment.

    PS has a threshold set up for each disk which is 8GB it can hold on cache anytime, if there is more data to be processed, it will stop receiving the data from source machines. This is by design of azure site recovery in order to avoid filling up the cache drive.

    Has this issue occurred before? If yes, this means that disk churn rate exists. The best way to solve this problem is to add a separate process server to the configuration server. Recommend you to move some of your source machine under that process server. Data will not exceed 8GB on one process server.
