High CPU crashing JSD instance

[Eric F]

Problem is happening every few days. 

JSD instance hosted on AWS is experiencing high CPU then becomes unresponsive, which requires reboot. 

Jira Service Management 4.20.8

Jira Software 8.20.8

Jira Core 8.20.8

Hi @Eric F 

When you look through both your server logs and the atlassian logs do you see anything specific happening at the time of the high cpu usage?

This could be pretty much anything as multiple services are probably running on the server both Atlassian and OS specific or other programs.

[Eric F]

could you please provide some guidance on which log to look at? There's nothing else running on the instance except for JSD. I was hoping not to have to dig through logs.

Well in general there will always be other background processes running on any server :) Any Operating System services or other applications managing the server could do contribute to it.

What OS are you using (Linux/Windows)?

You can find details on the logs from Jira here : https://confluence.atlassian.com/jirakb/useful-log-files-in-jira-1027120387.html

The one that probably gives you the most insight would be atlassian-jira.log*

If that doesn't really show anything specific you would need to verify your system logs (either eventviewer on Windows or like a syslog on Linux)

[Eric F]

Instance is running on Linux.

Does JSD have any dashboard to look at top talker/top listener?

I've retrieved gone through the logs. The atlassian-jira-gc.log shows the following around the time of high CPU:

Can someone at Jira support team please take a look?

I tried to create a support case with zip file uploaded, but I do not see any open tickets when I log into Atlassian website.

[Dirk Ronsmans]

@Eric F ,

If you haven't opened a ticket yet there won't be any yet.

if you have that support.zip file you'll have to create a new case at https://support.atlassian.com/contact

With log's I'm sure they'll be better equiped to take a look if there is nothing obvious going on (which for me it isn't)

I tried this option but only "ask the community" is available. Adding the URL does not help as it is a private link.

Hey @Eric F ,

It seems you tried to enter the support case as a cloud product. You'll have to select a Datacenter/Server product otherwise it it will ask you for your cloud instance url.
