Subject AW: AW: java.lang.OutOfMemoryError: Map failed
Date Tue, 02 Apr 2013 09:29:40 GMT
The output is from the root user. Are you running Solr as root?

If not, please try again using the operating system user that runs Solr.

Hmmm I checked it and it seems to be ok:

root@solr01-dcg:~# ulimit -v

Any other tips or do you need more debug info?
