Error 5754 BizTalk Server

A message sent to adapter “Windows SharePoint Services” on send port “” with URI “wss://” is suspended.
Error details: [Microsoft.SharePoint.Client.ServerException] The request message is too big. The server does not allow messages larger than 2097152 bytes.

This error was triggered by the Windows SharePoint Services receive location or send port with URI wss://.

Cause:
Via COM+ it is not possible to upload messages larger than 2 Mb (2097152 bytes)

Solution:
With the following powershell code you can increase this limit (in this case to 75 Mb)

$ws = [Microsoft.SharePoint.Administration.SPWebService]::ContentService
$ws.ClientRequestServiceSettings.MaxReceivedMessageSize = 78643200
$ws.ClientRequestServiceSettings.MaxParseMessageSize  = 78643200
$ws.Update()
