How many McAfee Agent can concurrently connect to ePO server to pull the daily DAT update?

There are nearly 3000 MA that pull the daily DAT update from ePO server and i notice many MA are unable to update and fails with the below mentioned errors.

error type: update

error code: unable to find valid repository

error type: DAT

error code: update failed as script download error occurred

error type: Update

error code: Deployment/update process encountered an unknown error

Can someone please help me to know how many McAfee Agent can concurrently connect to ePO 5.3 server to pull the daily DAT update?, and what will happen if the DAT download process from MA gets interrupted due to bandwidth issue, will it retry to download the entry DAT file again or will cause a corrupted DAT file issue?

When the agents gonna download .DAT to update their databases, they have a random time for download the update. The agents don't update at the same time. You need to check your agents connection with ePO.

What about the second question, when happened to download be incomplete, he's will retry to download again. You can define the minutes that the agent will try to download again in the agent policies.

If you feel you are running into a bandwidth issue enable randomization for the DAT Update task:

1. Navigate to the system tree

2. Click the Assigned Client Tasks tab

3. For the DAT Update task, in the Actions column, click Edit Assignment

4. Click Next

5. Click the Enable Randomization button and randomize over 5 minutes

Apache processes only 250 simultaneous connections, but the server should be processing these connections in milliseconds. Intel Security determined that this low number is adequate even for enterprise environments. However, please refer to the ePolicy Orchestrator 5.x Hardware Sizing and Bandwidth Usage Guide.

what will happen if the DAT download process from MA gets interrupted due to bandwidth issue, will it retry to download the entry DAT file again or will cause a corrupted DAT file issue?

Generally speaking the McAfee Agent tries to establish connection using one of these methods. If all these methods fail, McAfee Agent tries to connect again during the next ASC.
