=====================

Looking for some hints on where to start debugging...

FWIW the code is using the 'pg' library to work with a Vertica 10 database. The same code and client stack works perfectly against a Vertica 23 database, and the database code does not appear in the stack trace.

Given the above stack I have no idea what went wrong, endless loop?, out of memory ?.....

Node.js version

v21.2.0

Example code

No response

Operating system

Ubuntu

Scope

Runtime process crash

Module and version

Not applicable.

Jan 06 '24 00:01 markddrake

it seems like an issue is occurring in the csvLibrary.js file at line 34 and in the verticaWriter.js file at line 50.

Jan 07 '24 03:01 preveen-stack

@markddrake did @preveen-stack's suggestion help?

Attempting to Bite Tongue.... I'm afraid it did not tell me anything I was not aware of at the point i posted.

Jun 11 '24 01:06 markddrake

If it's still outstanding, can you provide a minimal reproducible example?

(FWIW the stack trace is from Node.js's CPP)

Jun 15 '24 10:06 avivkeller

This needs more info for 2 weeks. I'll be closing this issue if more information isn't provided in the next few days.

node program prints a stack trace then terminates. The stack trace is not a normal node stack trace (or at least if it is it's formatted very strangley)
