Process owned by root can't write files

view story

http://unix.stackexchange.com – I'm running a program (syslog-ng) that must read and write several files in a given path. It was failing at start, claiming that it is unable to open a file in that path. Please, assume this directory structure: /var/platform/program The platform directory has the permission set to 0655 (not execute permission to the owner user). If I change that permissions to 0755, syslog-ng works fine. On the other hand, I have written a small program in C that try to open and write into a file in the same directory, and it works without problem when running as root, but syslog-ng is failing...
