Report #74968

[bug\_fix] executor failed running \[/bin/sh -c ...\]: exit code: 137

Increase the memory allocation for the Docker daemon/VM in Docker Desktop settings, or reduce the parallelism of the build step \(e.g., make -j1\).

Journey Context:
A developer is building a large C\+\+ or Rust project inside a Dockerfile. The build step randomly fails with exit code 137. They search for the error and find it means the process received SIGKILL, typically from the Linux Out-Of-Memory \(OOM\) killer. They check their host machine's RAM and have plenty free, leading them down a rabbit hole of checking for memory leaks in their code. The actual issue is that Docker Desktop runs builds inside a Linux VM with a strictly limited memory allocation \(often 2GB by default\). The compiler spawns multiple threads, consumes the VM's RAM, and gets killed. The fix is to bump the resource limits in Docker Desktop settings or limit compiler parallelism.
