Problem Description

Typically, the missing threads issue will be discovered during analysis of a server hang problem or unexplained timeouts or other confusing and unexplained behavior. In a default WebLogic Server configuration, there should be 15 execute threads for the default queue (0 through 14). Following is an excerpt from a thread dump showing that ExecuteThreads 13, 8, 6, 5, and 3 from the "default" queue are missing. There is no exception, stack trace, or notification of any kind in the server log indicating that threads have died.
