Jira is going down with a simple issue search after the upgrade

[Neeraj Rath]

We have recently upgraded postgres Jira database from 13 to 15.7 and JIra 9.11.2 to 10.3.4
After the upgrade, nodes are going down frequently with heap memory issue. simple user search operations making jira server down.

In fact we tried to search issues and Jira is getting down. Any clues or anyone experienced it so far.

We are working with Atlassian team from last 4 days with no solution. It's happening in production.

Perform below checks:

3. Check out the Pool connection limit in dbconfig file (mentioned in link above)
