Jira Data Center is slowed after every time it's restarted

Question

We have a Jira Data Center 7.9.2 (3 nodes, each node has 32-core CPU, 30G RAM) with Oracle database.

The amount of JVM is 6G on each instance.

Our problem when happened that Jira is restarted. After that application is so slowed unreasonable. In this time the amount of CPU usage is 4~5 percentage with no load even at midnight.

During the day and with normal load CPU usage is 30% average with awful performance and so slow.

There aren’t anything in log files and this behavior is happened in each of instance the same.

Sometimes CPU usage is raising above 80% and Jira doesn’t response.

Mostly after a few days behavior of CPU is normal and Jira speed is without problem.

Is there any solution about my issue?

Hi @Hamid Gholami

This is one of those cases where we would want to create a support request for this issue.  I suspect our support teams will want to gather support zips from each node as well as thread dumps from these nodes when this slowness occurs to try to better understand what might be causing this performance issue.

This is something that you should be able to create yourself with a valid SEN.  I wasn't able to find any data center products on your account.  Perhaps you can follow the steps in How to find your Support Entitlement Number (SEN) in order to find the SEN for your data center site, and then use this to raise a support case in our https://support.atlassian.com/contact page.  Please select, technical support, Jira, Server, and then enter your SEN to make sure that your question is routed to our support team.

Hi @Kiran Panduga {Appfire} ,

Thanks for your response.

All of Jira Data Center (They are installed on CentOS 7) and Oracle DB are in same network and I checked their network, it's work fine.

Each of 3 nodes are checked locally (hostname:port)and there aren't any problem.

In during a day I haven't any scheduled cron jobs and we don't have  anti virus.

Thanks,

Hamid
