May be the same problem I had: sendfax ignoring SIGCHLD from (maybe
this
time also) faxcover. The problem occured when starting sendfax in the
context of lpd. 


sendfax wrapping program:

/*
 * This program starts sendfax with default handling of signal
SIGCHLD.
 * The reason is that lpd (and cron) sets this signal to be
ignored
 * which makes sendfax fail when creating faxcover.

#include <signal.h>
#include <stdio.h>
#include <errno.h>

#define SENDFAX         "/usr/local/bin/sendfax"

main( argc, argv )
int argc;
char **argv;
{
        signal( SIGCHLD, SIG_DFL );
        execv( SENDFAX, argv );
        fprintf(stderr, "%s: %s\n", SENDFAX, strerror(errno) );

        exit( 0 );
}
