Subject Re: Optimize fails with OutOfMemory Exception - involved
Date Thu, 22 Sep 2011 18:15:14 GMT

What is the best central place on an rpm-based distro (CentOS 6 in my 
case) to raise the vmem limit for specific user(s), assuming it's not 
already correct?  I'm using /etc/security/limits.conf to raise the open 
file limit for the user that runs Solr:

ncindex         hard    nofile  65535
ncindex         soft    nofile  49151
