I am hosting 2 sites on my iMac with OS X sever 3.0. I have two processes (httpd and xssendevent) with multiple duplicates. When the number of gets to about 20 or so, login and/or page loading is very slow. The only solution I have found is to reboot the Mac and server. What might causing this problem, how do I solve it? Thanks!
iMac (27-inch Mid 2011), OS X Yosemite (10.10.5)
