[syslog-ng]dns_cache problems with v1.5.13

[colm ennis]

hi all,

im currently using syslog-ng version 1.5.13. i have experienced problems
where negatively cached records were preserved indefinitely. only a full
restart would cause these ips to be resolved, even a hup would fail.

i've now turned off caching cos we rely on ips being resolved in these log
files.

impt part of the config attached,

thanks,

colm
