Ken:
I haven't gotten into that much detail. I've just been watching memory
usage on the Widows Task manager Performance window and seen it jumping up
continuously as the client runs. Maintains the memory level when it stops
and climbs again when I restart the client. I only reclaim the memory when
I stop the Apache service.
Thanks,
Theron

Theron:
How are you measuring the memory leak on the server-side? That is, is it a
constant leak per transaction or does the amount of memory leaked vary?
Thanks, Ken Krutsch

Yea
So if I run this is the client side code using a fresh generated Calculator
skeleton. Same on the server side with the addition of the code listed in
the documentation.
void main()
{
Calculator cal;
for (int y = 0; y < 10000; y++)
{
int result = cal.add(0, y);
printf(" %d \n",result);
//if (y % 10 == 0) printf ("\n");
}
}
Thanks much
Theron

Hi,
Could you give us the complete scenario please.
Are you creating an instance of the stub and then calling the same method
repeatedly or creating multiple instances of the stub ?
Perhaps you could just attach the code here?
cheers,
John.

memory leak
I was setting up my web service and I noticed that when I sent repetitive
calls into the service I was getting a significant memory leak. I decided
to go back and check against the calculator example and I noticed that it
also had the same problem with consistent memory loss when being used. Is
there some memory that I need to be freeing up somewhere that I don't know
about that isn't handled in the calculator example? Any help would be
greatly appreciated as this needs to be a fairly stable service. The
service and client are running on separate machines so I'm sure the memory
leak is caused by the service though I also get a memory leak with the
client.
Thanks
Theron
