Closed as program error.

Error description
WebSphere J2EE Servers that are running HTTP Transport
(also known as HTTP Catcher), may experience a problem where
the application server region is not properly cleaned up
when timer 'BBOC_HTTP_OUTPUT_TIMEOUT' expires.
.
When this timer 'pops' the server region should be ABENDed
with an ABENDEC3 RC=04130001.

****************************************************************
The HTTP Transport has a unique dispatch path through the
Control region.  This path differs from the GIOP workload in a
number of ways.  One difference is in the handling of timeouts
and the cleanup of the related requests.  For GIOP work queued
to WLM for delivery to a Server Region (SR), a timer is started
for the work based on the setting for OTS_MAXIMUM_TIMEOUT.  If
this timer expires prior to completion of the work in the Server
region, the Control region will build exceptions into the
Requests and abend the Server region (ABENDEC3, RC=04130001).
This recovery action is not happening for HTTP Transport work.

HTTP requests received over the HTTP Transport, where the
BBOC_HTTP_OUTPUT_TIMEOUT related timer expired, are not
interrupted and the associated SR is not abended.  This does not
allow control over long-running or looping requests from
consuming system resources.
Problem conclusion
Code has been modified to make the HTTP Transport request
timeout processing consistent with the GIOP request timer
processing. When an HTTP request received over the HTTP
Transport exceeds the timeout value specified by the environment
variable BBOC_HTTP_OUTPUT_TIMEOUT, the HTTP request will be
terminated as well as the associated Server region.

Explanation: An ORB_Request was Queued to WLM, but its
response was not received in a reasonable amount of time.
An ORB_Request Registry cleanup routine, HTTP(S) Request
Timed out, will cleanup the request.
User Response: Make sure that WLM can start the target
server region (it may be in a quiesced state).  Additionally,
check that the time out value is of sufficient length. See
the instructions in the WebSphere Application Server for
z/OS and OS/390 Customization and Installation Guide for
setting HTTP OUTPUT time out value via an environment variable
(BBOC_HTTP_OUTPUT_TIMEOUT).
