We have JIRA DATA CENTER with three nodes and with 200,000 issues. Also we use some of useful add-ons such as : Structure, Scriptrunner, eazybi, . . .
At some peak hours of consumption abnormally CPU usage goes up and number of established sessions on 8443 port without reason increase and does not decrease, so JIRA is very slow and not responding, so we must restart application and this happens repeatedly.
In JIRA log file we found two errors.
Can anyone help me on this?
