If the error happens in the external command, then you could configure
the pipe(8) daemon to run the command under strace and capture
strace output to file.
But, the pipe(8) daemon command-line syntax has limited options,
and it may be more convenient to configure pipe(8) to invoke a shell
script that straces the command.
#!/bin/sh
mkdir -p /tmp/pipe-debug
strace -o /tmp/pipe-debug/strace.$$ /your/command "$@"
