It does:
ipmon.c:1452
if (donehup) {
donehup =3D 0;
if (newlog) {
fclose(log);
log =3D newlog;
newlog =3D NULL;
}
}
And:
static void handlehup(sig)
int sig;
{
FILE *fp;
signal(SIGHUP, handlehup);
if (logfile && (fp =3D fopen(logfile, "a")))
newlog =3D fp;
init_tabs();
donehup =3D 1;
}
The only codepath I can see, that could cause this behavior, would be if th=
e=20
fopen fails, because newsyslog is holding a lock on the file at the time it=
=20
signals ipmon.
