Application crashes with Exception pointing to libgstapp_1_0_0!gst_app_src_end_of_stream

[hemanth.chandrashekar@in.unisy]

Hello,

We have one of our Windows application integrated with "G-Streamer 1.12.0"
and is running fine both on test/production system.

As the load on system/G-Streamer increases, we are facing the application
crash. On analyzing the dump file, it is pointing to one of the method call
from G-Streamer.

*** ERROR: Symbol file could not be found.  Defaulted to export symbols for

We are curious how to identify the root cause of this issue. Although it
takes some effort to recreate this issue, we can still see the problem with
load on the consistence failure.

I was reading in some portals if we can get some help without luck.
Appreciate if you can review and comment..

Code snippet where "gst_app_src_end_of_stream" is invoked ...

*static bool handleTerminateRequest(const wstring &reason,
VnmsStreamProcessor *proc)
{
	GstFlowReturn ret;
	/* we are EOS, send end-of-stream and remove the source */
	TR_TRACE( informTrace, 0, proc->Port << reason);
	ret = gst_app_src_end_of_stream((GstAppSrc*)proc->source);
	if (ret != GST_FLOW_OK) 
	{
		TR_TRACE( errorTrace, 0, proc->Port << L"handleTerminateRequest: error
pushing end-of-stream buffer : " << ret);
	}
	SetEvent(proc->hInputDataProcessedEvent);
	return FALSE;
}*

Regards,
Hemanth
