I'm afraid it didn't give me a clue but in case someone spots
something here it is:
Well /tmp looks ok to me, and doesn't contain any files
that are used for the communication before I try to start it.
[root@machine /tmp]# ls -al
total 12
drwxrwxrwx 3 root root 4096 Mar 30 17:08 .
drwxr-xr-x 21 root root 4096 Mar 29 11:44 ..
drwxrwxrwt 2 100 101 4096 Nov 28 22:08 .font-unix
