Core Dump Occurs on Program Exit When Using ibm_db in AIX Environment

[k1lowM]

On an AIX environment, when running a Node.js program using the ibm_db module, the DB connection and disconnection processes complete successfully, but a core dump always occurs when the program exits.

This issue is reproducible across multiple AIX servers and Node.js versions.

Test Environment

OS	Node.js	ibm_db
AIX 7.2.0.0	v18.12.1	3.1.0
AIX 7.3.0.0	v20.18.2	3.1.0

Test Code (ibmdbtest.js)

const ibmdb = require('ibm_db');

const connStr = "DRIVER={DB2};DATABASE=xxx;HOSTNAME=xxx.xxx.ibm.com;UID=xxx;PWD=xxx;PORT=xxx";

ibmdb.open(connStr, (err, conn) => {
  if (err) {
    return console.error('connect error!!:', err);
  }
  console.log('connect success!!');

  conn.close((err) => {
    if (err) {
      return console.error('close error!!:', err);
    }
    console.log('close success!!');
  });
});

Execution Result

• After running node ibmdbtest.js > db_test.log 2>&1, a core dump is generated.
• DB connection and disconnection complete successfully (confirmed via console logs).

Notes

• Changing the version of ibm_db does not resolve the issue.
• This does not occur on non-AIX environments (e.g., Linux).

Hi @bimalkjha , @ibmdb team,

Could you please take a look at this issue when you have a chance?
The problem still persists on AIX environments, and any guidance or workaround would be greatly appreciated.

Thank you!

@k1lowM Looking into it. Thanks.
