I am aware that version 0.19.3 is old. We have been having trouble getting
our infrastructure group to build out new nodes so we can have a rolling
upgrade with testing for both versions going on. I am now setting the
limit to 1048576 as per
http://stackoverflow.com/questions/1212925/on-linux-set-maximum-open-files-to-unlimited-possible,
however, I'm concerned this may cause other issues.
If anyone has any suggestions I'd love to hear them. I am using this as
fuel for the "please pay attention and get us the support we need so we can
upgrade" campaign.
