Questionmemset() run time error Pin

Hi all,
I am getting some "Access violation writing " for memset for every 30 min after i run my application.
And the cursor goes to the below line:

memset(pSharedBuffer2, 0, sizeof(*pSharedBuffer2));


Here is the function i am using i am trying,and this function i am calling in timer:

#define BUF_SIZE 2048
const int max_msg = 2048;
char *pSharedBuffer2 = (char*)malloc(max_msg);
int WriteToShared()
{
	
		HANDLE handleMappedFile;
		LPVOID lpMsgBuf;
 
		handleMappedFile = CreateFileMapping(INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, HIWORD(BUF_SIZE), LOWORD(BUF_SIZE), szName4);
		if (handleMappedFile == NULL)
		{
			printf("Could not create file mapping object.\n");
			LocalFree( lpMsgBuf );
			
		}
		memset(pSharedBuffer2, 0, sizeof(*pSharedBuffer2));
 
		pSharedBuffer2 = (char*)MapViewOfFile(handleMappedFile, FILE_MAP_ALL_ACCESS, 0, 0, BUF_SIZE);
		
		
		if (pSharedBuffer2 == NULL)
		{
			printf("Could not map view of file.\n");
			CloseHandle(handleMappedFile);
			
		} 
		
 
	sprintf(i,"%d",Test);	
	addMsg1(i, pSharedBuffer2);
	
	return 0;
OnTimer()
{
WriteToShared()
}

}


Can anyone guide,whats exactly going wrong.

Thanks
Sharan
