Standard issue SUN Java 6 on Debian. We run that JVM on all machines. But i see the same (error executing: ulimit -n) locally with Jetty and Solr trunk and Solr 3.5 and on a production server with Solr 3.2 with Tomcat6. > > > This is rather strange, it seems. lsof | wc -l is not higher than 6k > > right now and ulimit -n is 32k.

I get the correct output for ulimit -n as tomcat6 user. However, i did find a mistake in /etc/security/limits.conf where i misspelled the tomcat6 user (shame). On recent systems only ulimit and sysctl is not enough so spelling tomcat6 correctly should fix the open files issue. No we only have the issue of (error executing: ulimit -n). > > -- > Sami Siren -- Markus Jelsma - CTO - Openindex
