Describe the bug

A remote build suddenly errored out with

error: builder for '/nix/store/58jxr2x94kz4zq5x5gqffjsyz7kpxhgc-cargo-c-0.9.29.drv' failed with exit code 1
error: Nix daemon disconnected unexpectedly (maybe it crashed?)

On the remote builder (nix 2.18.2) I can find

Mar 25 18:20:04 build2 nix-daemon[1917]: accepted connection from pid 880823, user hexa (trusted)
Mar 25 18:21:43 build2 nix-daemon[880825]: terminate called after throwing an instance of 'nix::Interrupted'
Mar 25 18:21:43 build2 nix-daemon[880825]:   what():  error: interrupted by the user

A coredump was created due to SIGABRT

Steps To Reproduce

  1. Use the remote building functionality
  2. ???

Expected behavior

The assumption is that the SSH connection died. The error messsage could have been clearer.

The error was supposed to be transient. The connection could've been retried.

nix-env --version output

nix-env (Nix) 2.90.0-lix
