NoteHKLM\SOFTWARE\Microsoft\MSMQ\Parameters
| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0x0 - 0xFFFFFFFFMessages | 0x40 (64 Messages) |
Determines the maximum size of the message queue to each network session. The value of this entry limits the number and size of messages that can be stored between internal acknowledgments from the receiving server. If the queue fills before an acknowledgment is received, additional messages are discarded.
If the queue is too small, messages might be lost. Alternatively, because messages in the queue are released again when a session fails, a large queue can flood the system with duplicate messages.
Note
This entry does not appear in the registry unless you add it or use a program to change its default value.
