Nodejs terminate itself after client called RFC #189

valix999 · 2020-11-30T10:50:04Z

I found a problem with calling RFC that returns more than 1,200 records and makes the application terminate itself with no error log or any exception. As from the image parameter "IM_LIMIT_BRANCH" will limit the amount of returned records (my return records are "ET_BRANCH").
Are there any missing configs from my node-rfc client?

bsrdjan · 2020-11-30T11:02:10Z

Need more info on your node-rfc environment. Could you please run the following command in your node project root folder and post the output:

node -p "require('node-rfc').environment"

here are my node-rfc environment

The termination is the most likely related to one known bug in SAP NWRFC SDK PL7, causing accidental overwrite of RAM beyond string buffer boundaries.

Do you have the older SDK version at hand, like PL6, please try with that one.

Otherwise, please create a SAP standard support message for the BC-MID-RFC-SDK component, refer to this issue and request the preliminary shipment of the PL8 patch.

valix999 · 2020-11-30T12:43:21Z

Where can I find the PL6 SDK version, currently I follow this note (https://launchpad.support.sap.com/#/notes/2573790) and found only the PL7 version

bsrdjan · 2020-11-30T12:51:25Z

Only the latest SDK version is available, the PL7. The PL6 and older versions are not available.

valix999 · 2020-12-01T02:04:22Z

Do you have the release date of the PL8 version?

bsrdjan · 2020-12-01T12:40:49Z

This workaround should help with PL7 in the meantime.

Unpack the zip or tar archive and copy the sqpnwrfc.node to node-rfc\lib\binding folder:

node-rfc-v2.3.1-napi-v7-win32-x64.tar.gz

node-rfc-v2.3.1-napi-v7-win32-x64.zip

valix999 · 2020-12-02T10:34:03Z

I'm using new sqpnwrfc.node but it's still not working

bsrdjan · 2020-12-02T11:15:13Z

It could be a different error than and need some more info.

Could you please post your test script and the full console log, starting with the test script invocation and including any output, like:

C:>\test\node test.js

Did it work with older NWRFC SDK and which logon language is used ?

Does the function module works correctly in ABAP, with more than 1,200 records? You can test the ABAP remote function module in ABAP system, using test transaction SE37.

Can you reproduce the issue by calling ABAP standard remote function module or BAPI, not Z-module? Example with the module available in standard SAP system would help me locally reproduce and investigate.

You can also activate the remote ABAP debugging and run the node test script. When the ABAP debugger shows up, you can stop before the RETURN statement and check if ABAP processing completed and if all records are there.

bsrdjan · 2020-12-07T09:37:32Z

The test with the PL6 or PL8 is not necessary because the workaround we already tried did not help.

Before we close the support ticket 834664 / 2020, could you please update the ticket with the logon data, so that I can check the ZHHRC_INF_REF_DATA by myself? You could also prepare one test case in SE37, working with more than 1,200 records.

valix999 · 2020-12-07T10:49:16Z

The results in SE37 are working correctly with more than 1,200 records.
But the system refers to the incident is not where RFC - ZHHRC_INF_REF_DATA exists.
If I cannot find any solution, then I will re-open the incident again with another account.
Thank you.

bsrdjan · 2020-12-07T11:05:17Z

Thank you @valix999, I think that would be fastest/easiest way, if I can check directly by myself.

Please write in that new incident that it is created only to get the system access, for processing this GitHub issue (insert the url).

After the incident is created, please let me know also which input data to use for testing, to return more than 1,200 records.

Same problem happens to when calling
"RFC_READ_TABLE"
on CAUFV table
with this filter "FTRMI >='20210317"
it return in average 15 records.
Sometimes Nodejs terminate itself, no error message,

it happens 100% of times if returned records are 0;

No error occurred when reading full tables with 25k or more records.

I had no problem with v2.4.0 and pl7

1.2.0 is not compatible with my node v14 (it throws an exception), i tried any other library version still app crashes when calling "RFC_READ_TABLE"

gimapei · 2021-03-26T02:10:26Z

if you can using other nodejs.
you can change the node version to 12.x versing.
using 'n' lib

npm i -g n
2, n 12 or other version
node -v

.. I think it would be better to build a debug environment.

Hi,

just tested on Windows and Darwin and got no errors. Could you please test with the latest node-rfc and NWRFC SDK ?

If the termination still occur, does it look like a timeout (how long it takes?) and is there any message?

Environment

  noderfc: {
    version: '2.4.1',
    nwrfcsdk: { major: 7500, minor: 0, patchLevel: 8 }

Test script

Hi,

I am also facing the same issue with "RFC_READ_TABLE".

Node.js process terminates after reading 10000 data. I am getting data in chunks of 2000 so, after 10 RFC call to RFC_READ_TABLE it terminates.

I tested it with different node-rfc version but still i got the same error after fetching 10000 record.

Error:

exited with code [3221226356] via signal [SIGINT].

It seems there is an issue with memory allocation.

My Runtime:

{
platform: { name: 'win32', arch: 'x64', release: '10.0.19041' },
env: {
SAPNWRFC_HOME: 'C:\nwrfcsdk',

}

Thanks,

@rbhuva, need a test script to try to reproduce the issue. Please consider that using RFC_READ_TABLE is not recommended and the priority of processing related issues is lower.

Hi @bsrdjan,
Thanks for your comments.

To reproduce the issue, you can execute test_script attached

Hi @gimapei,

node-rfc version : "2.4.2"

rbhuva · 2022-02-08T09:58:44Z

Hi @gimapei,
Do you think any other version would help?

Thanks & Regards,
Rajdeep Bhuva

bsrdjan · 2022-02-08T10:58:22Z

Hi and sorry for the late reply. Could you please test with the RFC SDK PL9, released in Dec 2021 ?

gimapei · 2022-02-09T01:10:31Z

Hi rbhuva.
I think it's good to update.

I think most of the errors in my case were related to memory allocation in C++.
In particular, I think it's caused by the logic that frees up memory usage.
Therefore, if I commented on the part of memory-free logic from the source and compiled and used it myself,
the error would disappear.
At that time, the version was probably the early 2.x version.
Afterward, when I tested the version provided by bsrdjan, it was confirmed that the problem was gone.

If the error occurs even after using the latest version
how about making a code that connects RFC in java
and making a node wrapper and using it?

I've heard from my colleagues,
there is no error from Java lib.

Thanks
Joe

Hi @gimapei , @bsrdjan ,

Thank you for your help.
I got the issue. It was because, I followed functional approach to create client (function which will return RFC client).
Pool variable was getting destroyed as it was in function scope and I was returning just the client variable.
It got solved by preserving the pool variable by creating it at outer scope fixed this issue.

This is working fine and tested with latest version of node-rfc and SDK PL9.

Thanks,
Rajdeep Bhuva

Hi @rbhuva,

thank you very much for finding and sharing the root cause. It looks like a reproducible bug, that shall be investigated and fixed The issue remains open until that is done.

@rbhuva
Congratulation, It's great.
