Job Processor Errors with Large Files

[ThomasRambach]

I have a custom job processor job running that works fine for most files, but for large drawings it's generating errors. Not sure how to debug or figure out what's going on. Any ideas?

Here's the error:

3/3/2020 7:44:44 AM Job failed while processing. (Exception: Autodesk.Connectivity.WebServices.VaultServiceErrorException: 0

Server stack trace: 
   at Autodesk.Connectivity.WebServices.ServiceBase`1.ServiceProxy`1.Invoke(MethodInfo methodInfo, Object[] args, TServiceInterface obj)

  at OFC.Vault.JobProcessor.JobExtension.UploadFileResource(WebServiceManager svcmgr, String filename, Byte[] fileContents) in JobExtension.cs:line 1136

This is the offending code:

        public static ACW.ByteArray UploadFileResource(WebServiceManager svcmgr, string filename, byte[] fileContents)
        {
            svcmgr.FilestoreService.FileTransferHeaderValue = new ACW.FileTransferHeader();
            svcmgr.FilestoreService.FileTransferHeaderValue.Identity = Guid.NewGuid();
            svcmgr.FilestoreService.FileTransferHeaderValue.Extension = System.IO.Path.GetExtension(filename);
            svcmgr.FilestoreService.FileTransferHeaderValue.Vault = svcmgr.WebServiceCredentials.VaultName;

            ACW.ByteArray uploadTicket = new ACW.ByteArray();
            int bytesTotal = (fileContents != null ? fileContents.Length : 0);
            int bytesTransferred = 0;
            do
            {
                int bufferSize = (bytesTotal - bytesTransferred); //% MAX_FILE_TRANSFER_SIZE;
                byte[] buffer = null;
                if (bufferSize == bytesTotal)
                {
                    buffer = fileContents;
                }
                else
                {
                    buffer = new byte[bufferSize];
                    Array.Copy(fileContents, (long)bytesTransferred, buffer, 0, (long)bufferSize);
                }

                svcmgr.FilestoreService.FileTransferHeaderValue.Compression = ACW.Compression.None;
                svcmgr.FilestoreService.FileTransferHeaderValue.IsComplete = (bytesTransferred + bufferSize) == bytesTotal ? true : false;
                svcmgr.FilestoreService.FileTransferHeaderValue.UncompressedSize = bufferSize;

                using (var fileContentsStream = new MemoryStream(fileContents))
                    uploadTicket.Bytes = svcmgr.FilestoreService.UploadFilePart(fileContentsStream);
                bytesTransferred += bufferSize;

            } while (bytesTransferred < bytesTotal);

            return uploadTicket;
        }

Getting more clues. This is the error showing up in the ADMS FileStore logs that matches the error time with the Job Processor:

Exception(Inner): The maximum message size quota for incoming messages (52428800) has been exceeded. To increase the quota, use the MaxReceivedMessageSize property on the appropriate binding element.
Stacktrace(Inner):

Resolved.

I bumped the Vault server web.config maxReceivedMessageSize up to a much higher number and the issue resolved itself.
