There is a lots of connections even when you are not at scale. I have Sat6 running for few days and have synced RHEL6 + RH Common repos and registered ~10 systems and I see this:
# lsof | cut -d ' ' -f 1 | sort | uniq -c | sort -n | tail
344 tuned
420 named
636 Passenger
720 qpidd
1950 postgres
1975 mongod
3521 ruby
4070 httpd
6489 celery
56592 java
# lsof | grep elastic | wc -l
40320
Moving 6.2 bugs out to sat-backlog. This bug appears to be related to elasticsearch, which has been removed in 6.2. Marking as CLOSED/CURRENTRELEASE. |
