I tried to contact you on IRC, but you weren't there. I found another
exim4 process hanging today.

Here are the data, you want me to collect :

I killed the process (-9), stop the daemon, clean *.lockfile in the
/var/spool/exim4/db/ and start again the daemon.

Now, all seems to be ok.

If you have any idea ?
