Hi!
There are some new things I experienced with the previouse described problem:
Source-Machine: WindowsXP
Destination-Machine: Windows2003 Server
I wrote a simple java socket program and with this I didn't get any Socket
exception, while I'm opening more simultaniouse connections.
But if I just listen to the Port where STAF is running at the server, I get a
"SocketException: Connection refused".
Maybe this information helps something to find the problem!
Best Regards

Subject: RE: [staf-users] max number of simultanuous requests
Hi!
We contacted you some time ago regarding the problem "max number of
simultaneous requests". Finally I found the time to check your
solution-suggestion, but it didn't work for us.
First we even hadn't this TcpNumConnections parameter, but it didn't make any
changes when I added it to the registry.
I tried it now with different operating systems and if I execute the requests
from an WinXP to a Win2003 I get this Error submitting request, RC: 22.
But If I send the requests from Win2003 to Win2003 it is no problem. Even if I
execute if from Win2003 to WinXP it is no problem.
To reproduce it, I created a batch file with this staf-request "staf %1 ping
ping" and then I created another batch file which starts this batch file
several times like:
start testping.bat SOME_IP
start testping.bat SOME_IP
...
Maybe you can also reproduce it and give me some other solution!
Best Thanks in advance!
br,
Dominik

Is it possible that you are encountering a TCPIP limitation on your Windows
system? Can you open the Windows registry and check the TCPIP settings? The
following document has some information:
http://support.microsoft.com/default.aspx?kbid=314053. In particular check the
TcpNumConnections parameter.
Several years ago we helped someone with a similar problem (when running
multiple requests from a Windows system, a limitation was reached on the number
of remote connections). In their environment they were using a 10MB router
which was causing the limiation, and upgrading their router to a 100MB router
resovled the problem. Can you check your adapter/network settings?
On your Windows system, can you make more that 5 simultaneous TCPIP
connections? For example, telnet from the Windows systems to 6 remote systems
and see if that works.

What version of STAF are you running on these machines?
What's the output of: STAF someIP VAR LIST?
We submit many (> 6) simultaneous requests to an endpoint without issues.

[staf-users] max number of simultanuous requests
hello,
we are experiencing connection problems as soon as the number of nearly
simultanuous requests to a endpoint reaches the number of 6
we are using the event-service but even the command "staf someIP ping ping" is
not working.
here is the result we get in the 6th or above request
Error submitting request, RC: 22
Additional info
---------------
STAFConnectionWriteUInt: Error writing to socket: send() RC=10054: 22
for testing purposes we just tried to execute a batch process which calls other
batch files nearly simulatneously.
can you help us with this issue?
thx & br
Gottfried
