Describe the problem

When cockroach dies with panic(out of memory), this error does not reliably make it to the stderr redirecting log files.

To Reproduce

See #62763.

Expected behavior

Fatal errors from the runtime should reliably show up in the logs.

Environment:

  • release-21.1 and onwards (unclear if problem exists in 20.2)
  • Server OS: linux

Additional context

This adds friction to roachtest investigations.
