Re: java.net.SocketException: Too many open files

This is on Linux? This should help:

echo fs.file-max = 16384 >> /etc/sysctl.conf

On some distro's like Debian it seems you also have to add these settings to 
security.conf, otherwise it may not persist between reboots or even shell 
sessions:

echo "systems hard nofile 16384
systems soft nofile 16384" >> /etc/security/limits.conf

Re: java.net.SocketException: Too many open files

One note for this. I had a trouble to reset the root's limit in
Ubuntu. Somewhere I read, that Ubuntu doesn't give you even the
correct number of limit. The solution to this problem is to run Solr
under another user.
