Too Many Changes At Once In Directory

When placing a large quantity of files into a watched folder, you may see an log event something like this:

Too many changes at once in directory ...

As the wording suggests, this occurs because the buffer that tracks the changes in the folder overflows and cannot keep reporting changes to Umango.

Although the changes will eventually be picked up by Umango, there may be a delay of up to 5 minutes. To avoid this situation you can increase the buffer size. To do this, follow the instructions below:

• Open the registry and navigate to the key HKLM\SOFTWARE\Umango
• Right click on the key and select 'New/String value'
• Name the new String value 'WatchFolderBufferSize'
• Open the new string value and give it a value higher than 8192 that is a multiple of 4096 (not too high; perhaps 40960).
• Save the string value
• Restart the Umango Windows service
