Is KNIME Down Right Now?
KNIME is not down for most users right now. This page tracks KNIME status through reports from people who build workflows in KNIME Analytics Platform and run jobs on KNIME Hub. A sharp rise in reports usually means a Hub or executor problem is spreading.
Many KNIME problems start on your own machine. A locked workspace or a low memory setting can look like a total failure.
Is KNIME Down for Me or Everyone?
Try opening KNIME Hub in your browser first. If the Hub loads and shows your spaces, the service is up. Then start Analytics Platform again and watch where it stops. A hang at the workspace screen is local, every time. If the Hub also fails for a colleague, the outage is on the KNIME side.
Why KNIME Analytics Platform Will Not Start
The most common cause is a workspace that is still locked. KNIME leaves a lock file when it closes badly after a crash. It then warns that the workspace is in use and refuses to open it.
Close KNIME fully, check that no KNIME process still runs, and start it again. If the lock stays, point KNIME to a fresh workspace and import your projects.
Why KNIME Runs Out of Memory
Big tables and deep loops eat memory fast in KNIME. The default heap setting is low for heavy work. Rows then stop mid run with a Java heap space error.
Raise the memory limit in the knime.ini file inside the install folder. A value near half of your system memory works for most people.
Why Nodes Go Missing After an Update
Updates can leave extensions half installed. Nodes then show as missing or a workflow opens with red question marks. This hits community extensions more than core nodes.
Open the extension manager and reinstall the missing packs. If a workflow came from a teammate, ask which extensions it needs before you open it.
Executor and Hub Job Problems
Jobs sent to KNIME Hub run on executors, not on your laptop. An executor that shows offline will hold every job in a queue. Jobs also fail when the executor lacks an extension the workflow uses.
Check the executor status in the Hub admin area before you blame the workflow. If all executors are down for everyone, treat it as a KNIME outage.
Common KNIME Problems and Fixes
Clear a Locked Workspace
Quit KNIME and end any leftover KNIME process in your task manager. Start KNIME and choose your workspace again. If it still complains, create a new workspace and import the project folders from the old one.
Raise the KNIME Memory Limit
Open knime.ini in the install folder and find the line that starts with -Xmx. Raise the number, for example from 2g to 8g, and save the file. Restart KNIME and run the heavy workflow again.
Reinstall Missing Extensions
Go to File, then Install KNIME Extensions, and pick the packs your workflow needs. Restart the platform when the install ends. Open the workflow again and check that no node shows a question mark.
Restart a Stuck Executor
In KNIME Hub, open the executor view and check its status. Restart any executor that shows offline or busy for too long. Send one small test job before you queue the big work again.
Fix Hub Sign In Problems
Sign out of the Hub in your browser and in the KNIME Explorer view. Clear the browser cache, then sign in with the right account. If your team uses single sign-on, ask the admin if the provider settings changed.

Frequently Asked Questions
Why does KNIME say my workspace is already in use?
KNIME locks the workspace while it runs. A crash can leave the lock behind, so the next start thinks another copy is open. Close every KNIME process and start again.
Why does KNIME get stuck on the loading screen?
A plug-in that failed to load is the usual cause. Starting with a clean workspace often gets past it. You can also start KNIME with the -clean flag to rebuild the plug-in cache.
How do I give KNIME more memory?
Edit the knime.ini file in the KNIME install folder. Change the -Xmx value to a bigger number, such as -Xmx8g. Save the file and restart KNIME.
Why are nodes missing in my KNIME workflow?
The workflow uses an extension that is not installed on your machine. Open the extension manager and install the missing packs. Workflows shared by teammates often need community nodes. KNIME shows the missing node names when the workflow opens.
Why does KNIME Hub show my executor as offline?
The executor service stopped or lost its link to the Hub. Restart the executor from the Hub admin area. Check that the machine that hosts it is on and can reach the internet. If every executor is offline, the Hub itself may be down.
Why do my KNIME jobs fail on the Hub but work locally?
The executor is a different machine with its own setup. It may lack an extension, a driver, or access to your files. Read the job error in the Hub and match it against your local setup.
