We are using RTD Win32 SDK to fetch skill set statistics. We are facing a memory leak in the NIrtd_singleDataRequest call. I have described the problem below. Has anyone faced the same issue? The AACC version is 6.4.16 (SP16) . Is this a known issue and was fixed in a later release?


Problem Description: Memory leak detected in the NIrtd_singleDataRequest call

The function NIrtd_singleDataRequest seems to allocate two Table Group object as per the NIrtd_getCnt. We could free only one object using NIrtd_freeTableGroup. In the following code snippet, we are displaying the counts before and after the NIrtd_singleDataRequest function call. The output of the code also given below.

As seen, the TGCnt before the call is 0 and after the call is 2. However, after calling the NIrtd_freeTableGroup function, only one TG object is freed and the another remain unallocated thereby leaking memory.


=========================
Code Snippet
=========================

void zDisplayDebugCount(const char *dispStr)
{
printf("================================ \n");
printf(" --- %s --- \n", dispStr);
printf("================================ \n");

printf("Query Count %d \n", NIrtd_getCnt(QueryCnt));
printf("Conj Count %d \n", NIrtd_getCnt(ConjCnt));
printf("TG Count %d \n", NIrtd_getCnt(TGCnt));
printf("Row Count %d \n", NIrtd_getCnt(RowCnt));
printf("Value Count %d \n", NIrtd_getCnt(ValueCnt));
printf("Cache Count %d \n", NIrtd_getCnt(CacheCnt));
printf("Name Count %d \n", NIrtd_getCnt(NameCnt));

return;
}

void main()
{
/* Some code is removed for brevity */

/* --------------------------------------
** Call API
** ------------------------------------
*/
zDisplayDebugCount("Before NIrtd_singleDataRequest Call");

*RetCode = NIrtd_singleDataRequest(&tableGroup, &authPtr,&query);

zDisplayDebugCount("After NIrtd_singleDataRequest Call");

NIrtd_freeTableGroup(tableGroup);

return;
}




Output of the program:

================================
--- Before NIrtd_singleDataRequest Call ---
================================
Query Count 1
Conj Count 0
TG Count 0
Row Count 0
Value Count 291
Cache Count 2
Name Count 291
Compression was ON - data uncompressed successfully.
================================
--- After NIrtd_singleDataRequest Call ---
================================
Query Count 1
Conj Count 0
TG Count 2
Row Count 0
Value Count 291
Cache Count 2

Hello,

I am seeing exactly the same thing and puzzling over what to do about it. Do you have a workaround?

We are just living with it. We don't have much volume, so we restart the servers every night to release memory.

There's a newer release under AACC7 which (as I understand it) is compatible with AACC64. If you have the capacity to try that, please do, otherwise would you open a support ticket with us and I can at least check it against AACC7

Thanks, but I am seeing this with the 7.0.3 version of the RTD SDK.

And the other, equally serious, issue we are seeing is that NIrtd_singleDataRequest eventually hangs without timing out, after several hours of periodic use (every minute).

If you could open a support ticket via [...]

[...] it would allow me to pull this into my queue and investigate.
