Issue with test-cluster-disconnect-handles.js

[imran-iq]

There is currently an issue with the test test-cluster-disconnect-handles.js where the debugger gets an EADDRINUSE error and does not exit and therefore does not release the port it is using. This causes an issue when running

tools/test.py --mode=release --progress=tap parallel

As the port is not released and tests continue to run causing a large number of tests to fail with EADDRINUSE too.

Sample output:

imran@tp-iqbali ~/node/node_main ./out/Release/node --debug=12346. --expose_internals test/parallel/test-cluster-disconnect-handles.js
Debugger listening on port 12346
Error: listen EADDRINUSE :::12346
    at Object.exports._errnoException (util.js:915:11)
    at exports._exceptionWithHostPort (util.js:938:20)

    at listen (net.js:1272:10)

    at Object.start (_debug_agent.js:21:9)
    at startup (node.js:72:9)
    at node.js:976:3
(Process stays running until explicitly killed)

Output from lsof before running the test:

imran@tp-iqbali ~ lsof -i :12346
imran@tp-iqbali ~ 

And after

imran@tp-iqbali ~ lsof -i :12346

Making sure I have no running node instances before running the test

imran@tp-iqbali ~ ps -ef | grep node

And after running the test

imran@tp-iqbali ~ ps -ef | grep node

I have ran into this issue on multiple machines.

This is on linux x86-64, with e4e5b13 checked out from master branch

Using ubuntu 14.04
output of uname -a

Linux tp-iqbali 3.13.0-53-generic #89-Ubuntu SMP Wed May 20 10:34:39 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Same here on S11.3 with v5.1.0

[imran-iq]

Issue is fixed by simply not specifying --debug on the command line

imran@tp-iqbali ~/node/node_main ./out/Debug/node  --expose_internals test/parallel/test-cluster-disconnect-handles.js
imran@tp-iqbali ~/node/node_main

Issue seems to be fixed with #4009 and #4084 closing issue
