Hello,

I'm loath to ask a question right off the blocks but I wasn't able to find too much in the archives about this...

I'm using syslog-ng 1.5.14 and am trying to get the 'dns_cache(yes);' option to work for me. When compiled with -DNSCACHE_DEBUG I get this message to start with...

initialising nscache: 1007 entries, 3600/60 expiration.

... but no messages to suggest nscache_lookup() or any of the other cache functions are ever being called. Is there more to this option than meets the eye?

Other recent discussions have talked about using djb's dnscache or nscd to do this instead and questioned the wisdom of using caching internal to syslog-ng. Should I not be using this feature? Does it, in fact, work at all?
