Max call of service

2008-08-19 Thread Michael Sutter

Hello list,

I have a problem with a Axis2 service and need some input if my service 
is developed the right
way. Inside my service I make a call to a external library. So I make a 
variable of the object and
put it on the stack. So normally the instance should be destroyed when 
the scope is lost. I think
this is done when the execution of the service is finished and the 
output is given back to the client.

Am I right?

By doing this I had a strange problem. The mentioned service is called 
every 10 sec to give a state
to the client. First I was running the service in Axis2 version 1.4 and 
get about every two hours an
AxisFault: Too many open files. So I think that the destructor of my 
variable was not called and that
I have memory leaks. After that I integrated a log message in the 
destructor to see, if it is called.
Normally my service is running inside an Apache installation and I never 
saw the output of the log

message.

Nevertheless if I run the service in axis simple server I see the log 
output and so I think the implementation
of my service is correct. When running the service inside the axis 
simple server I also get AxisFault,
but after about 12 - 14 hours runtime. After searching the mailing list 
I found, that there is a memory
leak in the mod_axis apache modul. So I compiled Axis2 from SVN and the 
service is running for about

17 hours without any problem.

So to my question: Have I done something wrong in the implementation of 
my service by putting the instance
on the stack and not explicitly calling the destructor or could it be 
that the SVN version fixes the problem?
Nevertheless, why I'm getting the message by running the service inside 
the axis simple server, where I

see that the destructor is called?

Kind regards
Michael

Hello Supun,

sorry for that. The stack is not created by me. It is the normal program 
run-time stack from the service and the

object is not created as a global variable.

The code looks like this:
adb_getStatusResponse_t *
axis2_skel_DAQStatus_getStatus(const axutil_env_t *env)
{
 try {
   FdDaq fd_daq;
 }
 catch (...) {
 }
 return return_node;
}

where fd_daq is the object.

Kind regards
Michael

Hi Michail,

The stack the you mentioned is little bit confusing. Is it the stack 
in a normal process run-time or a stack that you have created? If it 
is the stack in a normal program run-time where are you creating your 
object in the code? Are you creating the object as a global variable?


Thanks,

Hi Michael,

By looking at your code it seems that it doesn't lead to a memory leak.
Every time that function is called the object will be created and when the
function finishes execution the object will be destroyed. I think there is
another memory leak in your code. But I doubt that your problem is a result
of a memory leak. Can you please send your log file?

Hello Supun,

what log file do you mean - the axis.log or the error log of the apache?
Nevertheless, I don't found the exception in the log files and they contain
a lot of messages as the log level is set to trace.
Also I think that the service is running fine with the svn version, 
maybe it was

a fixed memory leak with the apache module.

Kind regards
Michael

Normally the created resources are deallocated when the local object get
destroyed, i.e. when you finished execution the function, as Supun noted.

Can you start the apache server on valgrind and check whether you hit any
memory leaks? Hope you do have access to a linux box.

Re: Max call of service

2008-08-19 Thread Michael Sutter
I think the message is from stderr and the my first opinion was that the 
loading of the library cause
the problem. So I asked if it is correct to put the object on the stack, 
which should be no problem as

you told.

@Rajika The access to a linux server is no problem, the service is 
running under linux. I never used

valgrind , but it is a good suggestion and I will try it.

Kind regards
Michael
