Enterprise Capture Server Experiences High CPU Usage And Hangs While Recognizing 2-D Data Matrix Bar Codes (Doc ID 2235904.1)

Last updated on JULY 07, 2017

Applies to:

Oracle WebCenter Enterprise Capture - Version 11.1.1.9.0 and later
Information in this document applies to any platform.

Symptoms

The Capture servers CPU spikes when processing the batches with the Data Matrix bar codes, and over time causes the server to hang.  The Capture diagnostic log displays:

The instability issues started happening around the same time that they started using a new capture workspace (BDMailProcessing).  The major difference in this workspace this one pulls data from a Data Matrix bar code to a metadata field. All the other workspaces are using bar codes for document separation.  When releasing a batch to the Recognition Processor, the CPU usage for the Capture process increased to around the 20 -30% range and stayed there while it processed the batch. The batches on average have 250-350 pages.
