Memory fault in Axis2C
Hello,
We are trying to run Axis on Unix platform. However, when we try to invoke the 'echo' webservice, the Axis server crashes giving a memory fault. In the mail below I have explained the findings I derived after debugging Axis2c:
1). I had built the libecho.so file using the following files : echo.c, echo.h and echo_skeleton.c
2). The Axis2 Log clearly states that the "libecho.so loaded successfully".
3). The processing of the request proceeds till the statement :
File: msg_recv.c
Function: axis2_msg_recv_make_new_svc_obj Code Lines:
if (impl_class)
{
AXIS2_SVC_SKELETON_INIT((axis2_svc_skeleton_t *) impl_class, env); } axutil_allocator_switch_to_local_pool(env->allocator);
4). the Code exits and the Axis server crashes. I have also made sure that the functions are built inside the libecho.so file. It is not an empty linkable.
Please help me out here. I am not able to figure out waht is going wrong here.
Regards,
Shivam.

Hi Shivam,
Are you running simple axis2c server or running axis2 apache module in
Apache2?. I am asking this because the code line
*axutil_allocator_switch_to_local_pool(env->allocator);
*
has meaning when only running as an Apache2 module. If you are running
in Apache2 please run in simple axis2 server and tell us what happen.
Also make sure to run your server with trace enabled (Build axis2/C with
trace enabled and run server with option -l6) and send us the resulting
server log file.
thanks,
Damitha

What is the version of Axis2/C you are using?

RE: Memory fault in Axis2C
Posted by "Gupta, Shivam" <sh...@hp.com>.
Hi,
I have built the samples using Eclipse IDE. I have attached the Makefile that was used by Eclipse to build the objects. As far as the trace is concerned, there is nothing stated in the log files. The last message recorded is that " libecho.so loaded successfully.".
Please help me here,
Regards,
Shivam.

Hi Shivam,
Can you send the backtrace of the crash? Did you compile the samples of your own or are you using the same set of samples coming with the distribution ?

RE: Memory fault in Axis2C
Posted by "Gupta, Shivam" <sh...@hp.com>.
Hello,
I think I have already taken care of assigning the Skeleton init function to the service_init function. The below code is an extract from the echo_skeleton.c file:
static const axis2_svc_skeleton_ops_t echo_svc_skeleton_ops_var = {
echo_init,
echo_invoke,
echo_on_fault,
echo_free
};
axis2_svc_skeleton_t *
axis2_echo_create(
const axutil_env_t * env)
{
axis2_svc_skeleton_t *svc_skeleton = NULL;
/* Allocate memory for the structs */
svc_skeleton = AXIS2_MALLOC(env->allocator, sizeof(axis2_svc_skeleton_t));
svc_skeleton->ops = &echo_svc_skeleton_ops_var;
svc_skeleton->func_array = NULL;
return svc_skeleton;
}
Moreover, I have not changed anything in the code. So I think there is no possibility of me not setting some code parameter. There would be some other issue.
I hope this helps you in guiding me.
Thanks,
Shivam.

Please check weather you have defined the init function of the service and set it to the service skeleton.
The method signature of this function is:
int AXIS2_CALL echo_init(
axis2_svc_skeleton_t * svc_skeleton,
