SELinux is already disabled.
cat /etc/selinux/config | grep -v "^#"|grep -v "^$"
SELINUXTYPE=targeted
SELINUX=disabled

Yes, also the redirected log file is empty. Also kernel log is empty.

I tried to redirect it to a different, new file, on startup I get nothing, 
after killing it I get:
2010-09-03 16:35:39.177 GMT [2149] @/: LOG:  could not stat "/usr/share/doc/xalan-j2-manual-2.7.0/apidocs": No such file or directory

Any ideas?

BTW: Shared memory can't be any issue?

Ciao,
Gerhard
