All servers (lb and back ends) are Centos 7. I have increased the number of open files on the LB to 4096 (because I got errors on messages last month) but I haven't done any change on the back ends. I will check if there is any error related to the number of files on the back ends. Thanks. On Dec 28, 2015 22:33, "David Martineau" <[email protected]> wrote:
