Well, strace does add overhead, so you might look at the strace to see what is exec'd that you could test ps for. It is probably on your terminal even if disconnected from your shell.
If any of the files is per-run and is closed at the end, you might be able to make a named pipe the target and track its life by the cat of the output out of the named pipe. Strace can tell you what is being closed at the end, too.
Calling fuser on files can find user processes, but it is a bit slow.

safe_asterisk
SAFE_ASTERISK(8) Linux Programmer's Manual SAFE_ASTERISK(8)
NAME
safe_asterisk -- A wrapper to run the asterisk executable in a loop
SYNOPSIS
safe_asterisk [ asterisk_params ]
DESCRIPTION
safe_asterisk is a script that runs asterisk in a loop, which can be useful if you fear asterisk may crash.
The script does not run in the background like a standard service. Rather, it runs in its own linux virtual console (9, by default). It
also uses the option '-c' of asterisk(8) to avoid detaching asterisk from that terminal.
safe_asterisk also runs asterisk with unlimited core file size, and thus asterisk will dump core in case of a crash.
To get a "picture" of console 9, from another terminal (e.g: from a remote shell session) you can use:
screendump 9
The init script of the Debian package should be able to run safe_asterisk as the asterisk service, if so configured. See coments in
/etc/default/asterisk
FILES
/tmp
safe_asterisk runs in that directory, rather than in / as usual.
/tmp/core
If core files were generated there, they may be
/etc/asterisk/startup.d
Files in this directory will be 'source'd by the safe_asterisk script before it starts Asterisk proper, allowing them to set addi-
tional environment variables or run any other steps that are needed for your system.
BUGS
While showing the output on a console is useful, using screen(1) as the terminal may be better.
The script does not read configuration from standard location under /etc
It uses fixed locations under /tmp , and thus may be exposed to a symlink attacks.
