There are other variations on this code, such as repeatedly calling a callback with setInterval with a 1ms delay that also cause this problem. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Edit: I tried both with v0.5.10 (unstable) and v0.4.12 (stable) and the unstable version performs a little bit better---the stable version just stops outputting to the console but continues to consume memory, whereas the stable version continues executing and consuming memory without pause. node.js - Do While Loop . I could setup a cron job to run the app at the specified time but I'd prefer to run it with node index.js and have it run constantly, doing nothing until it's the right day and time and then going back to "sleep" until the following day.. How do I achieve that? Download the finished blend file and support my channel at https://patreon.com/chrisp - THANK YOU! First, run an infinite loop, then run the GDB command. Also called as exit-condition loop. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. If this probe fails a 4th time, the K8s scheduler pronounces the container as dead and replaces it in the pool. Do you think having no exit record from the UK on my passport will risk my visa application for re entering? A for statement looks as follows:When a for loop executes, the following occurs: 1. [...] event loop … This expression can also declare variables. You probably have no use for it most of the time but in this specific case, GDB proved to be extremely useful. Statement 3 increases a value (i++) each time the code block in the loop has been executed. You can see the output is an infinite loop of nextTick callback calls, ... At the start of a new iteration of the event loop, NodeJS invokes a system call to get the current clock time. Now you know how to get the infinite loop’s stack trace, you can use it in the production container. This is unexpected behavior. The application runs as stateless, so after the container restarts, you lose all the data in memory and storage. I can imagine that with long-running daemons under load a similar memory leak would occur, although I haven't tested it. This article describes the solution that worked for us. Event Loop Explained. That is a dramatic improvement in memory and it's slightly faster too IIRC. Ben Lubar Gamers last edited by . I'm surprised setInterval doesn't work this way too; calling a function with a short delay causes the same memory leak. The answer by @VyacheslavEgorov seems right on but I would guess that deferring to the event loop would solve the problem. The environment manages multiple concurrent event loops, to handle API calls for example. The root cause is a bad guard in gyp/pylib/gyp/input.py that doesn't take into account that '' in 'whatever' evaluates to True. How exactly does process.nextTick() work? As mentioned above, our loop was caused non-deterministically, so we used the liveness probe command to find it. Colleagues don't congratulate me or cheer me on when I do good work. Our app uses the AWS Elastic Kubernetes Service (EKS), which is easily compatible with the Elastic File System (EFS). How many presidents had decided not to attend the inauguration of their successor? I am a beginner to commuting by bike and I find it very tiring. HTML5 Spec describes a standard set of guidelines vendors could use to develop browsers/JavaScript runtimes or other associated libraries.
