: Anyone encounter a problem when changing their hostname? (via : /etc/conf.d/hostname or just the hostname command) I'm getting this error : when going to the admin screen, I have a feeling it's a simple fix. It : seems to work when it thinks the machine's name is just 'localhost'.
i don't think this is a tomcat or solr issue ... it looks like a basic java/dns issue (that can most likely be reproduced with a 4 line commandline java app for testing) Take a look at the InetAddress jvadocs, specificly the info on Caching. my guess is either: 1) your reverse name lookup doesn't match the name you are using which causes the getLocalHost call to freak out becuase it can't do a DNS lookup on the hostname it thinks it is. 2) you changed the name while the JVM was running, and the "forever" cache is returning a name that no longer exists. -Hoss
