hm, normally the list of open_basedirs do also contain the lock-file...
have a look at the /var/www/fcgid/master/php5(or 4)/php.ini:
open_basedir = "/var/www/ispcp/gui/:/etc/ispcp/:/var/run/ispcp.lock:/proc/:/bin/df:/bin/mount:/var/log/rkhunter.log:/var/log/chkrootkit.log:/usr/share/php/"
Would be fine if you could explain this. On a fresh, new debian + ispcp this should not happen. Did you import some older files?
the lock file is in the list since 2007-07-31
