sendmail's newaliases dies on SIGFPE

Hello everybody,


This morning I discovered my sendmail daemon wasn't accepting incoming
connections anymore. I tried a telnet on it and no sendmail banner at all:

[root@monpc etc]# telnet 127.0.0.1 25
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
Connection closed by foreign host.


So I decided to restart the sendmail service but I got an floating point
exception error message:

[root@monpc ~]# service sendmail restart
Arrêt de sm-client*: [ OK ]
Arrêt de sendmail*: [ OK ]
Démarrage de sendmail*: /etc/init.d/sendmail: line 46: 22620 Exception
en point flottant /usr/bin/newaliases > /dev/null 2>&1
[ OK ]
Démarrage de sm-client*: [ OK ]


The line 46 is launching newaliases. I tried to launch newaliases from
the command prompt and it fails with a status 136:

[root@monpc etc]# newaliases
Exception en point flottant
[root@monpc etc]# echo $?
136




An strace showed me it was ending on an SIGFPE error:

Any idea what's wrong there ?

I've verified the package with rpm -V sendmail but nothing wrong appeared.

By the way, my OS if Fedora 9 and I've the sendmail-8.14.2-4.fc9.i386
RPM installed.

After a hard reset of my machine sendmail and newaliases are now working
well. I guess my machine has some hardware problems.

Cheers,
FC.
