By slow startup I mean just bringing up solr, xmlui and jspui can take 60 minutes. I think this is due to /dev/ramdom on the OS not getting sufficient entropy, probably caused by the Bouncy Castle crypto APIs or the new SecureRandom() in Eperson. performing a find / as root appears to unstick the JVM on startup, pointing to an entropy issue (find / will cause disk I/O not from cache generating low level device driver entropy) Has anyone else seen these issues ? Is there a known fix (other than performing a find) I have already tried -Djava.security.egd=file:/dev/./urandom -- This message is automatically generated by JIRA.
