It also persisted in this state through multiple machine resets and I wrangled with this for over an hour. JavaScript heap out of memory is a common issue that occurs when there are a lot of processes happening concurrently. Happy to provide more debugging info if needed. I think child compiler + watch mode = fatal heap memory error. This mode will minimize memory usage but introduce a performance cost. { test: /.tsx?$/, loader: 'ts-loader' }, I'm sending out an occasional email with the latest programming tutorials.

Here's an example of increasing the memory limit to 4GB: node --max-old-space-size=4096 index.js If you want to add the option when running the npm install command, then you can pass the option from Node to npm as follows: This is in addition to { splitChunks: { chunks: 'all' } }, Ie: Looking inside my webpack script (version 4.43.0) I did this instead: this worked locally and in my jenkinsfile. extensions: ['.mjs', '.js', '.jsx', '.json', '.ts', '.tsx'], 1: 00007FF6C646D1BA v8::internal::GCIdleTimeHandler::GCIdleTimeHandler+4506 The build process just runs a command to build a react app using webpack. If I turn off the plugins I have (python-requirements), I still get the same problem. cache.idleTimeout denotes the time period after which the cache storing should happen. In most cases this is fully sufficient and might reduce the memory consumption. So I'm quite sure that the memory leak is somewhere in the individual packaging part (maybe the file copy). The issue is caused by a memory leak in postcss-loader. - subnet-0c92a13e1d6b93630 I have 10 lambda functions in Python without dependencies, the dependencies are in 4 layers also in the same setup.

I was helping out a friend on his project and I had to rollback to 5.3.5 to see some stability with the out-of-memory issue. Adding additional memory to the process worked for a while, but, when the complexity of my system grew, the system reached a point where I had to provision more than 12GB for the process not to trigger any faults (and I'd have had to keep increasing it whenever new functions were added). It always compiles at least once without running out of memory, but crashes on the second or third recompile after a file changes. Once serialized the next read will deserialize them from the disk again. Sure but it's like reinstalling your OS or getting a new laptop - it might fix the issue, but it's not much of an answer.

Hi @daniel-cottone , I don't even understand why this is an issue here. - subnet-031ce349810fb0f88 In this paper, we propose a framework, called JS Capsules, for characterizing the memory of JavaScript functions and, using this framework, we investigate the key browser mechanics that contribute to the memory overhead. mysqlHost: entry: entries, You can add an environment variable through Control Panel to increase the memory allocated to a Node.js project. Name for the cache. path: /api/util/api-key-generator Find centralized, trusted content and collaborate around the technologies you use most. rev2023.3.3.43278. From there it worked great for me. My first question: what does the number 1829 (and 2279) represents exactly ? I'll just opt to not make use of individual packaging for now. For my tested JS project, the memory showed roughly the same fill state before and after the webpack run. I still would want to package functions individually to get more optimized bundles but it is not my priority at the moment. This is important since webpack cache files store absolute paths. If I use fork-ts-checker-webpack-plugin, my machine dies as the plugin spawns like 30 workers in parallel and it eats my 16GB RAM/swap in few seconds IMHO the only solution is to compile all functions in series, one after the other, by default or with setting. region: eu-west-2 Hi, Im having this same issue. If/when this does get fixed I can turn it on then. It improves performance by quite a bit in the testing I have done. Heres the full error I was receiving when running ./bin/webpack-dev-server, no I have no idea how it got into this state. Does anyone here know, if there is a good node performance analyzer (profiler), that can track the heap and the GC (best would be graphically), so that I can see when it starts to allocate objects? If that works, we have to find out, where exactly the memory leak comes from and if it can be fixed by reusing objects. This is vague - what version of postcss-loader has the memory leak? You can set the default memory limit using your terminal clients configuration file. Because I was quite annoyed by this point, I just nuked the whole thing. Check the memoryLimit option in the ForkTsCheckerWebpackPlugin configuration. So in the worst case memory usage is lambda count * memory limit. better optimization-wise, but webpack itself is invoked only once and does Do roots of these polynomials approach the negative of the Euler-Mascheroni constant? You should change that too. - subnet-0a5e882de1e95480b I had to bump up the RAM to 7GB for it to work. - subnet-0c92a13e1d6b93630 This might indicate that it isn't "just" a webpack watch issue because webpack is still watching all my files, it is just not compiling all my files every time due to the caching plugin. timeout: 30 I don't think I can declare anything else of significance other than having only 9 functions. My build is not passing through CI and I do not want to go back to https://github.com/prisma/serverless-plugin-typescript because it is using an outdated version of typescript and appears to be looking for maintainers.

SLS-webpack since 3.0.0 requires that you use slsw.lib.entries for your entry definitions and have the function handlers declared correctly in your serverless.yml in case you use individual packaging. The only step where memory consumption increases (but is always cleaned up by the GC) is the actual zipping of the function packaged.

The first try should be to disable some plugins in the webpack.config and check if the ts-loader might allocate all the memory. I think changing the title to "JavaScript heap out of memory when _packaging_ many functions" makes more sense now that it has been isolated to just the packaging process and not the deployment process. When I'm working with a webpack-dev server, the problem sometimes occurs.

Not the answer you're looking for?

The overall size of the project is a very small project, I run projects much bigger with webpack with the same loaders (and more stuff) and almost never fall on this heap errors (the last I remember was back on webpack 1), so I don't think the solution here should be focused on changing the loaders configurations, but on the way that serverless-webpack is executing webpack. - sg-0a328af91b6508ffd events: By clicking Accept all cookies, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our Cookie Policy.
