Re: [monit-dev] Resolver issue

[Martin Pala]

Hello David,

monit doesn't cache the resolved names nor nameservers - it uses the (libc's) 
getaddrinfo() interface to resolve the hostnames when necessary. Please can you 
provide more informations about the system so we can try to replicate the 
problem? (platform, OS, version). Do you use nscd? (name service caching daemon)

Regards,
Martin
