IN attchmanent: x axis: time y axis: Number of open apache connections Work around: Increase number of apache connections limit cat /etc/systemd/system/httpd.service.d/limits.conf [Service] LimitNOFILE=20000 systemctl daemon-reload systemctl restart httpd This is just a workaround. Would be interesting to find out why do we need these many apache connections Hi Pradeep, is this a dupe of bug 1328984 ?

Created attachment 1153694 [details] apache scale Description of problem: Every new host registration takes huge number of apache open connections on satellite. I started registering hosts in bunch of 50's concurrently to satellite. After 700-800, satellite server rejects all new registrations due to lot of open apache connections. As shown in attachment, for every batch of 50, number of open apache connections increases. Once it reach 110 open apache connects, satellite stops accepting any new registrations. lsof | cut -d ' ' -f 1 | sort | uniq -c | sort -n | tail <snip> 110534 httpd Version-Release number of selected component (if applicable): How reproducible: Steps to Reproduce: 1. Scale satellite 2. 3. Actual results: There are too many apache open connections per registration. For every 50 host registrations about 4k-5k apache open connections are left. Expected results: Not many apache open connections Additional info:
