Start Riak crashing after 30 seconds

$ riak start crashing after 30 seconds of its start. I'm having following (changes) settings in my riak.conf:

search = on
storage_backend = leveldb
riak_control = on

crash.log contains the following:

Riak's internal solr use localhost and 127.0.0.1 as default host. So it should have defined in /etc/hosts file:

127.0.0.1 localhost

FYI, if you use windows your hosts file location could be different.

  1. Make sure the ports used by Solr are available. The defaults are 8093 for search, and 8985 for JMX.
  2. Tune your system to improve performance. Follow Improving Performance for Linux.
  3. In riak.conf, increase the JVM's heap size, the default of 1G is often not enough. For example, search.solr.jvm_options=-d64 -Xms2g -Xmx4g -XX:+UseStringCache -XX:+UseCompressedOops (see Search Settings).
  4. On a slow machine, Solr just may take longer to start. Try increasing search.solr.start_timeout.

Solr directories must be writable (usually /var/lib/riak/data/yz*), and a compatible JVM be used.
