[syslog-ng] s_tail not working

Hi, I am using syslog-ng 2.0.9 on my opensuse 11.1 box. I was trying to configure my apache log to be logged in syslog-ng. I used below syntax: source s_tail { file("/var/log/apache2/access_log" follow_freq(1) flags(no-parse));}; destination logserver { tcp("192.168.1.184" port(1470)); }; log { source(s_tail); destination(logserver); }; It gave me below error:

Mar 18 04:08:09 sugar3 syslog-ng[22107]: Follow-mode file source not found, deferring open; filename='/var/log/apache2/access_log'

Help would be appreciated. Regards, Nikunj
