WebCenter Enterprise Capture Is Not Processing Documents, with High CPU and Memory Utilization, and Stuck Threads (Doc ID 2697488.1)

Last updated on AUGUST 07, 2020

Applies to:

Oracle WebCenter Enterprise Capture - Version 11.1.1.8.0 and later
Information in this document applies to any platform.

Symptoms

WebCenter Enterprise Capture is not processing any emails, faxes or scanned documents. The documents are in the queue, but not processing.

There are several different kinds of errors repeating in the logs including:

<[STUCK] ExecuteThread: '54' for queue: 'weblogic.kernel.Default (self-tuning)' has been busy for "1,021" seconds working on the request "Workmanager: default, Version: 0, Scheduled=false, Started=true, Started time: 1021470 ms
", which is more than the configured time (StuckThreadMaxTime) of "1,000" seconds in "server-failure-trigger". Stack trace:
java.io.WinNTFileSystem.getBooleanAttributes(Native Method)
java.io.File.isDirectory(File.java:849)

oracle.odc.util.FileFolderList.next(FileFolderList.java:78)
oracle.odc.importprocessor.folder.FolderSource.pollForWork(FolderSource.java:149)

 

The stuck threads later become unstuck:
