APAR status
Closed as program error.

Error description
When running a java program on a distributed platform (windows,
aix, sun) accessing an initial context on WebSphere for z/OS,
z/OS does not respond when contacted.    The Daemon on WebSphere
for z/OS generates a "Internal communications error:
REASON=C9C20C1F." in the system output for the daemon.

To determine if the response message will fit in the allocated
buffer, we determine the buffer length by looking at the first
four bytes, as if they were a sequence octet.  However, the
first four bytes do not contain a length; instead, they contain
the ASCII text 'GIOP' or '47494F50'x.  When added to the buffer
address, this value may, if the buffer address happens to be
greater than '38B6B0B0'x, result in an end-of-buffer address
beyond '80000000'x, which appears to be negative when used in
a conditional.  This results in a determination that the
reponse will not fit in the allocated buffer; the BBOU0051E
message is then being issued and the request fails.
Problem conclusion
The buffer size calculation has been modified to use the actual
buffer length rather than incorrectly examining its contents to
determine the length.

APAR PQ60280 is associated with SERVICE LEVEL W401055 of
WebSphere Application Server V4.0.1 for z/OS and OS/390.
