Sync failing

Sync failing

Postby ericvolkelbarno » Fri May 26, 2017 5:17 am

Good morning,

For the last week we have been having a problem with syncing at some of our remote stations. We are seeing two different errors in the log, and the batch never sends to central:

5/25/2017 3:37:01 PM, (0) : Object reference not set to an instance of an object., Station ID: 999999999:Sess 5 (999999999).
5/25/2017 3:50:09 PM, (4921) Error uploading batch: (57) (Volkel-Barno, Eric | 5/25/2017 3:32:13 PM) Unable to write data to the transport connection: An existing connection was forcibly closed by the remote host., Central Site: 999999999, Station ID: D478L37448:Sess 5 (999999999).

Has anybody ever seen this before? Any clues what is wrong? Any ideas how to fix? We have been working on this for about a week, and run into so many brick walls that I now have a concussion.

Any help will be very greatly appreciated.

Thank you, eric volkel-barno

Some else strange is that when the sync fails the following message appears on the Kofax web server:

System.Web.HttpException (0x80004005): Maximum request length exceeded.
at System.Web.HttpRequest.GetEnterRawContent()
at System.Web.HeeptRequest.get_InputStream()
at Kofax.ACIS.IISForwarder.Post.PostFile(HttpContext oClientContext, String strFilePath, Int32 nACICacheID)

Update: The one problem has been corrected by increasing the size allowed by the web server. But... here is why is was failing in the first place...

Some of the batch classes are importing pdfs and making the file sizes big, and other batch classes are importing the very same pdfs and the file size is reasonable. (Incidentally, does anybody know what is up with the "t" files? as in there being a 1.tif, and a 1t.tif?)

Example - Large File Size from PDF Import
1.tif = 24,655 KB
1t.tif = 36 KB
2.tif = 24,655 KB
2t.tif = 63 KB
3.tif = 24,655 KB
3t.tif = 22 KB
4.tif = 13,501 KB
4t.tif = 25 KB

Example - Reasonable File Size from PDF Import
1.tif = 703 KB
1t.tif = 36 KB
2.tif = 1,058 KB
2t.tif = 63 KB
3.tif = 425 KB
3t.tif = 22 KB
4.tif = 380 KB
4t.tif = 25 KB

Example - Print Document and Scan using BC that produces large size from pdf
1.tif = 22 KB
2.tif = 26 KB
3.tif = 43 KB
4.tif = 15 KB

Thank you,

eric
