We have had multiple server crashes in the past 6 weeks (4 in Site1, 1 in
Site2, 3 in Site3) ...
All were preceded by multiple occurances of EventID 2022.
Our lead network administrator has applied the reg hacks suggested here (see
msoft posting below) and found no benefit.
Is there any means of determining ...
a. what or who is 'consuming the connections' at our 3 sites
b. when this consumption occurs ...and who is consuming connections when the
crash occurs..
c. when this consumption is near the maximum capacity of our server
This is a complex problem which we spent countless hours on...and we really
need a solution... or a fresh look at the problem.
We have over 100 software applications over about 500 pc systems...many of
which connect to about 75 different databases
We have a couple applications which write database records to a Jet3.5
(Access97) at a rate of about 10 per second continously for perhaps up to a
week..every second of every day. But we only started having these
EventID2022 errors. And we only started getting network crashes.
What tools exist to monitor server 'connections' so that we can track down
the source of this EventID 2022 ??
thx

SYMPTOMS
When you are using a computer running Windows, you may receive the following
error message:
Event 2022: Server was unable to find a free connection 1 times in the last
60 seconds.
CAUSE
This behavior occurs because the Server service is unable to keep up with
the demand for connections.
RESOLUTION
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.
To work around this issue, use the following steps:
Start Registry Editor (Regedt32.exe).
Locate and click the following registry key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\LanmanServer\Parameters
On the Edit menu, click Add Value, and then add the following registry
value:
Value Name: MaxFreeConnections
Data Type: REG_DWORD
Value: Any Value Up to 100 (in decimal)
On the Edit menu, click Add Value, and then add the following registry
value:
Value Name: MinFreeConnections
Data Type: REG_DWORD
Value: Any Value Up to 32 (in decimal)
Quit Registry Editor.
NOTE: You must restart the computer for the changes to take effect.
MORE INFORMATION
A special resource task in the Windows service uses the MinFreeConnections
and MaxFreeConnections value settings to preallocate connection objects.
Under certain conditions, the demand for preallocated connection objects may
exceed the default number configured in the MinFreeConnections and
MaxFreeConnections value settings.
However, you may also receive the "Event 2022" error message due to certain
system problems (for example, if the computer stops responding). You should
correct any system problems before you consider changing the
MinFreeConnections and MaxFreeConnections value settings.
