[syslog-ng] Using mount file as source

Hi. Using syslog-ng OSE, is it possible to use a remote file (ie: samba share) as source file? Doing it with a local file works like a charm, but using a mounted remote file does not work (with follow_freq set to 1 or not set). The file will be read by syslog-ng only if I make a ls on the folder where the file is mounted, or cat the file. Otherwise, syslog-ng seems to not see any change in the file. Thanks. G.
