Server Error
Read error 0



This happens once in a while out of the clear blue sky.

Any idea what can cause this?   I get this but the WAA Server appears to
still be running.   If I stop it and start it again, the problem is solved.
I really can not afford to have it down.

Maybe there is a way to have some kind of program checking for status of WAA
server and restart it when not available?

Is it possible to somehow stop WAA1SRV.EXE by passing a parameter or
something?

Do I have to setup something for the number of connections I may have at one
time?   I am planning in setting a point of sale system with maybe up to 60
users linked to it.

REM File: STARTWAA.BAT
REM
REM Purpose: Setting environment variables for
REM          WAA1SRV.EXE
REM

SET WAA_WORKERTHREADS=5
SET WAA_HOST=localhost
SET WAA_PORT=80
SET WAA_TRACE=OFF
SET WAA_DEVMODE=OFF
SET WAA_INTERNAL_LOG=OFF

start %1 waa1srv.exe                                               <====
What is the parameter?  Can not find any info on it.



Thank you for your help.

Richard,

Other people report this, but no reason or solution has been found yet.

In one of your packages, add a form-function with a really weird name:

Function YourMotherWasAHamsterAndYourFatherSmeltOfElderBerries()
   QUIT
   RETURN TRUE

Next, craft a web page on your desktop which calls this function.  e.g.

<html><head>
<script>
var url = "http://192.168.xxx.xxx/cgi-bin/waa1gate.exe";
var pkg = "MyPackage";
var fnc = "YourMotherWasAHamsterAndYourFatherSmeltOfElderBerries";
document.location=url+'?WAA_PACKAGE'+pkg+'&WAA_FORM='+fnc;
</script>
</html>

Click on the web page to shut down WAA.

Alternatively, you can use my WAA relauncher app (#27 on my site).  This
shuts down WAA then relaunches it.  I use this to restart WAA twice a day,
and I don't have the problems you are having

You might want to increase the number of worker threads, but with 60 users
I doubt it.  Keep an eye on the statistics page of the WAA console.
Ideally you want 3 times as many threads as your peak load (this gives you
lots of room for safety).

Additionally, you might want to download my WebStats package (#68) which
will analyse your WAA logs and tell you lots of things about the way your
packages are being used that you would never have guessed at.  One of the
most important things it does is estimate the capacity based on the number
of threads and overall usage (capacity being expressed in the average
number of requests WAA can service per hour based on the average time to
service a request as reported in your logs).

This is in case you want to do something like this:

c:\>startwaa xppdbg

...which launches WAA in the debugger.

Thanks a million Phil!  I am new at WAA and staggering

Got the blasted Server Error - read error 0 again.

It appears that the solution is to have a polling program running that will
get a returned value from the DLL, if it does not get it, it means the
server
got disconnected and it is time to restart waa1serv.exe.  Can anyone think
of a better way to do this?

Similar concept, different method.

In your package-dll's _register() function, launch a new thread which opens
a socket to another machine and sends an 'ok' signal and drops the
connection.  If it can't open the socket (the host application isn't
available), just ignore the error.

Set this thread to re-start every 15 seconds.

On your desktop, run an app which listens for the connection from that
thread.  If it doesn't receive a connection from WAA within 35 seconds, it
has missed 2 attempts and so there is a problem with WAA.

The resources required by WAA to run this thread and send the signal are
minimal, including CPU and network resources.

Phil Ide

I changed my log settings so it gave me more detail as to what is going on.
The following is the error I get reported to the log when I get the

I, too, have been plagued by the "socket write" error.  In my case, it is in 
one application, in one section, and has one predictable behavior.

The section has to do with registering people for meetings and collecting 
the attendance fee money.  There are six steps in this process.  The process 
will run flawlessly for three complete iterations of this process, however, 
after the third instance of executing step 6, sometime in the fourth 
iteration of the process, and it can be at any step, there will be a socket 
write error involving a thread that does not appear to be involved in 
processing any request.  I plan to start trial and error searching for the 
damning thing, but at the moment, we are busily booking people for a meeting 
later this week, so it will have to wait a few days.  Right now the great 
solution is that we run three credit cards and restart WAA.  Most 
perplexing, an earlier version of this code never had any socket write 
error.

Also, all other processes in this application run correctly all of the time. 
It is something about crossing my Rubicon of step 6 that is the problem.

Flailing about here trying to figure out why my application is trying to 
write something when it gets the socket write error.  From the WAA 
documentation..."After :footer() is called in a form-function, the function 
must return .T. (true) to instruct the WAA server to send the assembled HTML 
page."
Question:  Does it matter what value(s) are returned by any child 
function(s) called within the DLL function called via the hidden input 
"WAA_FORM"?  I have assumed that, so long as the _register() ref'd function 
returns .T., it does not matter, as in this example.  Wrong?

FUNCTION  CUSTOMER_INFO( oHtml, oContext )
   oHtml:put([<html>])
   oHtml:put([<head></head>])
   oHtml:put([<body>])
   oHtml:put([<FORM  NAME="fS" onsubmit="return Validator(this)" 
ACTION="/cgi-bin/waa1gate.isa" METHOD=POST>])
   customer_basic( oHtml, look_up_name( ) )
   oHtml:put([<input type=hidden name="WAA_PACKAGE" value="MY_DLL">])
   oHtml:put([<input type=hidden name="WAA_FORM" value="SAVE_CUSTOMER">])
   oHtml:put([<input type=submit value="SAVE CHANGES">])
   oHtml:put([</form>])
   oHtml:put([</body>])
   oHtml:put([</html>])
return .T.

FUNCTION  LOOK_UP_NAME()
    ...magical stuff to locate proper record...
return ( CUSTOMER->LAST_NAME )

FUNCTION  CUSTOMER_BASIC( oHtml, cLastName )
    oHtml:put([Name:&nbsp;<input type=text name="m_LAST_NAME" value="] + 
cLastName + [" size=20>])
return nil

Bruce,
yup!
Well, that should read as you are correct in your assumptions - your 
code-snippet is correct!
Apart from that I - personally - would prefer writing "procedure" instead of 
"function" if there is no returnvalue (like in your CUSTOMER_BASIC-function)

Regards,
Martin

One solution to Socket write error problem is attached.

Reads log file.  If it finds "Socket write error", stops
waa1srv.exe and restarts it.

Attached is a procedure I just put together, minus some of my functions
which I am sure you can replace.

What it does:  Every 2 seconds reads the latest waa1nnnn.log file and looks
for text "Socket write error".  If it finds it, it stops WAA1SRV.EXE and
1.5 seconds later, it starts it back up.

Uses a process.exe that I found from a free download site.  Works good.  I
still believe problem is a WAA1SRV.EXE bug.
