BBOU0051E Internal communications error: REASON=C9C20C5F
 Technote (FAQ)
 
Problem
Customer received message:

BBOU0051E Internal communications error: REASON=C9C20C5F

while deploying an ear file.
 
Cause
The use of medium weight threads caused the issue and it was resolved by adding the
following to the current.env files for servers running the jvm:
JAVA_THREAD_MODEL=HEAVY
 
Solution
Customer received abend SDC3 when deploying application with following message:


BBOU0006E CB SERIES SERVER WSPNMPM ENDED ABNORMALLY, REASON=C9C21235.

In Systems Management Server log, received:


Trace: 2003/02/28 22:52:42.984 01 t=8E08C8 c=UNK key=S2 (0000000A)
Description: Log Boss/390 Error
from filename: ./bboocomm.cpp
at line: 7663
error message: BBOU0051E Internal communications error: REASON=C9C20C5F.

The C9C20C5F is an internal communications error where
"comm_outbound_request - failed OTS sending request". This has been
seen by customers at sub-W401400 level. It turns out the use of medium
weight threads caused the issue and it was resolved by adding the
following to the current.env files for servers running the jvm:
JAVA_THREAD_MODEL=HEAVY

This can be added to Systems Management server and the Application server.

The fix to use heavy weight threads for Java as the default
has shipped as internal defect MD14270 into the V404 initial release (W401400).
