Error description

  • The netcdctrl -f(flush) option does not work. For
example,

 # netcdctrl -t dns -e hosts -f
 # netcdctrl -t dns -e hosts -a /tmp/netcd_dns_hosts

/tmp/netcd_dns_hosts still shows cached entries.

When you enable netcd debug, you will see "Exiting
flush_cache" just
after "Entering flush_cache" without cache related logs.

: cache_type = 1, map_type = 4
Tue Aug 20 11:14:04 2013 [xxxx] 1832:Exiting flush_cache
