When you try to save a message that is larger than 18 MB
from the Orchestration Debugger in Microsoft BizTalk Server 2004, you may
receive the following error message from the Health and Activity Tracking (HAT)
tool:
The following error occurred when extracting
variable information from the Runtime:
Only one usage of each socket
address (protocol/network address/port) is normally permitted
This problem occurs because new TCP ports are opened every
time that data is read from the message stream across the remoting boundary.
When remoting opens and closes a TCP connection, it takes four minutes for the
connection to finally close. This time delay is dictated by RFC-793 Section
3.5.
Warning If you use Registry Editor incorrectly, you may cause serious
problems that may require you to reinstall your operating system. Microsoft
cannot guarantee that you can solve problems that result from using Registry
Editor incorrectly. Use Registry Editor at your own
risk.
We recommend that you save live messages from the
HAT Operations view. However, to resolve this problem, you can use one or both
of the following methods:
Method 1: Adjust dynamically allocated ports
The
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\MaxUserPort
registry key determines the upper limit of the socket number that can be
dynamically returned. By default, the upper limit is 5000 unless you specify
the upper limit. You can increase this number, but it costs some kernel memory.
To do this, follow these steps:
- Click Start, click Run,
type regedit, and then click
OK.
- Locate and then expand the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
registry key. - Locate and then right-click
MaxUserPort.
- Click Modify, type the appropriate value,
and then click OK.
Note The valid range of this value is 5000 through 65534
(decimal).
Note You must restart your computer for this change to take
effect.
Method 2: Adjust port reserved time
The
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\TcpTimedWaitDelay
registry key determines how long before the port is available for use again. By
default, this value is 4 minutes. The recommended value is 30 seconds. To set
this value, follow these steps:
- Click Start, click Run,
type regedit, and then click
OK.
- Locate and then expand the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
registry key. - Locate and then right-click
TcpTimedWaitDelay.
- Click Modify, type the appropriate value,
and then click OK.
Note The valid range for this value is 30 through 300 (decimal), and
the time value is in seconds.
Note You must restart your computer for this change to take
effect.
