Using V4.0 Client code on Windows, customer attaches to queue 195 as primary queue (SQ in QCT). Then configure pams_get_msg with PSYM_MSG_LARGE, and large_area_len greater than 0x8000 (32769 or greater). The first message received has 32 nulls prepended to message. Subsequent messages are OK. If detach/reattach, again first message received has 32 nulls prepended to message. If the large_area_len less than 0x8000 (32768 or less), the error does not occur. These must be the first clients to attach after the CLS is started. Once the CLS has received a pams_get_msg from a client with parameters, large_area_len set below 0x8000, or without PSYM_MSG_LARGE, then all subsequent attaches by other client processes, followed by any pams_get_msg (even with large_area_len greater than 0x8000) no longer have this symptom for the first message receive.
