Red Hat Bugzilla – Bug 1311249
Max number of java open connections when registered content hosts are at scale
Last modified: 2016-08-18 12:32:39 EDT
Description of problem:
Registered close to 2000 content hosts to satelitte server. tried multiple times concurrent connections as well ( 50, 100, 150, 200)
Noticed max number of java connections opened.
lsof | cut -d ' ' -f 1 | sort | uniq -c | sort -n | tail
[root@satserver elasticsearch]# ulimit -a | grep open
open files (-n) 1024
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Register content hosts in scale
Too many open connections
Expected to be lesser open connections
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
# lsof | grep elastic | wc -l
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.
