Error E8522

Failed to receive data from the agent.

Module

Task

Reason:

This error message indicates that Arcserve Backup could not receive data because the socket could not be reset or it timed out.
When browsing the Windows server during a VSS job, the browse process for a writer stops responding and then fails when the timeout value has been reached.

Action:

Perform one of the following options to help resolve this issue:

By default, the socket times out after 1200 seconds (20 minutes).
1. Increase receiving and sending timeout settings from the registry key below.
```
\\HKEY_LOCAL_MACHINE\SOFTWARE\ComputerAssociates\Arcserve Backup\Base\Task\Remote
ReceiveTimeOut DWORD 3600
SendTimeOut DWORD 3600
```
2. Check the status of the network, and the CPU and network utilization of the target machine.
By default the time out value for the VSS thread is 20 minutes.
1. Try to reestablish the connection.
2. If you still cannot establish the connection, start the Client Agent service and try again to successfully browse without a timeout failure.
3. If the problem continues, you may want to modify the VSS browse timeout setting. This is a configurable parameter. You can manually create a DWORD registry value for “BrowseVSSTimeOut” in
```
HKLM\Software\ComputerAssociates\Arcserve Backup\ClientAgent\Parameters
```
  and specify a different value for the VSS timeout parameter.
Determine if the connection and firewall settings have changed.
Ensure that the driver for the network card is up-to-date.
If there is more than one network card, use a different network card and then resubmit the backup. For virtual machine environments, create a new network interface, and then resubmit the backup.
