VS Code Remote-SSH plugin gives out-of-memory error when connecting to CSC supercomputers

Connecting to CSC supercomputers using VS Code versions 1.101 and later may fail with error Out of memory: Cannot allocate Wasm memory for new instance. There are three workarounds to avoid this issue:

  1. Add to your .bashrc file on CSC supercomputers the line export NODE_OPTIONS="--disable-wasm-trap-handler", or
  2. increase login node virtual memory limit by adding the line ulimit -v "$(ulimit -Hv)" to your .bashrc file on CSC supercomputers, or
  3. downgrade your VS Code version to 1.100.
