Jira Dashboard crashes

Hello!

Almost every day jira Dashboard crashes(or being slow), cant load dashboard gadgets and jira lose all functionality till restart, except login is still working and page header with dashboard menu loads.

Right before dashboard crashes there is coming in new events in atlassian-jira-slow-queries.log(around 1000 ms to run query, sometime a bit more/less) when jira dashboard crashes events not coming in anymore.

Is there any suggestions to resolve this issue, or maybe can answer how slow log work, what can be reason for not writing new events.

Hi Ella,

The slow queries log will tell you which queries too a long time to run.  There is an article that can help you understand the underlying performance issue titled Troubleshooting Performance Problems.  I would start by doing the following:

  1. Download and install the scripts located in https://bitbucket.org/atlassianlabs/atlassian-support/.
  2. Execute the scripts during periods of slowness or unresponsiveness and provide the resulting tar.gz file to support.
  3. Select 'Y' to thread dumps.
  4. Run the disk speed tests with the same scripts, which are covered in more detail in the Testing Disk Access Speed KB.

When that is done, you can analyze the thread dumps using the Fastthread.io site if that works for you.  In the thread dumps you should see top (process) output.  You can use this to help you identify the threads that are causing issues as well by doing the following:

 

  • take the PID of the top 10 threads which are using CPU time and convert them to hexadecimal. Eg: 11159 becomes 0x2b97.
  • Search up the Hex values in the thread dumps to figure out which threads are using up all the CPU.

If you're unable to determine the source of the issue it may be helpful to create a Support ticket so the JIRA team can take a look at your logs when this happens and analyze the thread dumps on their end!

Cheers,

Branden
