Quiting ionic serve leaves the node process still in memory

[nickwinger]

I'm on a windows 7 machine runnig ionic serve nightly build.
If i quit ionic serve by pressing "q" or "quit" the node processes are still in memory taking up 1GB of memory.
I have to manually quit them via the task manager.
Funny thing:
although ionic serve got quit, if i make changes to the code the watcher seems to be still there and triggers on the command line.

not killing the processes manually and starting ionic serve again spawns new node process, taking up tons of GB all in all.

Expected behaviour:
Quiting ionic serve should kill all related node processes.

Please update the ionic cli and let us know if this is still an issue. npm install -g ionic@latest. ionic --version should be 2.1.12.

Thanks,
Dan

Hi Dan,

i'm afraid the problem ist still there.

When i kill the node process with the Task Manager in the Console Window where "ionic serve" was running i get the following output:

This issue is quite long present, i believe after switching to webpack.

having it on my win7 machine:

$ ionic info

Your system information:

 ordova CLI: 6.4.0
Ionic Framework Version: 2.0.0-rc.3
Ionic CLI Version: 2.1.12
Ionic App Lib Version: 2.1.7
Ionic App Scripts Version: 0.0.46
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 7
Node Version: v6.9.1
Xcode version: Not installed

[Simpler1]

Same as: #416 Unable to quit the build script like before

[danbucholtz]

@ataraxus, @Simpler1, we'll take a look. It definitely exits on Mac. Is there an easy way to validate on Windows?

[ataraxus]

Pretty easy just run ionic serve exit after its done via q or ctrl-c and have look at the task manager ctrl-shift-esc

[ataraxus]

@danbucholtz i investigated this further and have to correct my statement above. I dont get this if i use the default win7 CMD. i only get this if I use cygwin, which is a commonly used bash emulator for win7. nevertheless it used to work with cygwin before.

@nickwinger any chance that you are also using cygwin?

[nickwinger]

No, i'm running stock windows 7 command line

[ataraxus]

maybe this is some sort of race condition, i do have a quite underpowered machine ...

Happens to me after CTRL-C'ing out of ionic run android --device -l

Here's ionic info:

Ionic Framework Version: 2.1.0
Ionic CLI Version: 2.2.1
Ionic App Lib Version: 2.2.0
Ionic App Scripts Version: 1.1.3
ios-deploy version: Not installed
ios-sim version: Not installed
OS: Windows 10
Node Version: v7.6.0
Xcode version: Not installed

If I do a ps -n node (powershell) right after CTRL-C:

PS C:\> ps -n node

Handles  NPM(K)    PM(K)      WS(K)     CPU(s)     Id  SI ProcessName

Sometimes there are 3 processes, sometimes 2. This is starting from a state where no oother apps are already running node processes.
