Workaround for sync error “is more then 20 MB”

Solved369 views20th October 2026alarm storm notices Synchronization erros

Hi DOJO,

I have a Visio file that is bigger than 20 MB. During the midnight sync, the file fails to be synced across the cluster because it exceeds the 20 MB size limit, which generates an alarm. As a result, currently I have an alarm storm on the system due to these alarms.

Is there a way to allow this file to be synchronized despite exceeding the 20 MB limit, which would also prevent the synchronization error notifications for this specific file?

Kind regards,

Yes, the max size can be increased in the MaintenanceSettings.xml:

<MaintenanceSettings>
<Documents>
<MaxSize>20</MaxSize>
</Documents>
</MaintenanceSettings>

The size is in MB, but be carefull not to put it too high, because syncing very large files puts extra load on the system.

Hi Tom,
Thank you for the reply. Is there a way to change this setting, for example, via SLNet client test tool? I would like to avoid having to restart the DMA

Tom Van Bruaene [SLC] [DevOps Member] commented 20th October 2026

There's a SetDataMinerInfoMessage that works:

var request = new SetDataMinerInfoMessage
{
DataMinerID = dmaId,
What = (int)NotifyType.MaxDocumentSize, //145
Var1 = 50, // MB
};

DataMinerID needs to be -1 for the local dma or the correct dmaID to send to another agent in the cluster (best to keep the value consistent in the entire cluster

You can check that it work by seeing the value applied in Maintenancesettings

Thank you, Tom! That is exactly what I wanted
