"Too many open files" error

[Tony Webster]

Using Litespeed v4.2.20 Enterprise with a Magento site - getting thousands of of instances of error messages like "
/tmp/cache/0/1/d/01dd5f6001971fef: open() failed: Too many open files" every day - is there a fix for this?

Using Ubuntu 14.04.1 LTS (64 bit), PHP Version 5.4.35.

Really close to going back to Apache or Nginx - Litespeed is costing us significant downtime!

probably a permission issue introduced from Magento. can you try
#chmod -R 777 /tmp/cache/
for a quick action.
after the change, restart lsws. see if these errors still there.

Is it a VPS (openvz)? CloudLinux?
seems there are limits enforced on open files.
If openvz is used, you need to check /proc/user_beancounters , increase the limit with high failure count.
If you use CloudLinux, you need to make sure "nobody" user or the user that lshttpd running as is not limited by LVE.

Make sure your OS open file limit is high enough.
