Should we need to increase pool-max-size if databsae monitoring shows that max connection reached


Our Jira data center is throwing '500 Sorry, We had some technical problems during your last operation' intermittently.

We are getting errors like this when commenting or changing lables or any operation.


org.springframework.transaction.CannotCreateTransactionException: Could not open Hibernate Session for transaction; nested exception is net.sf.hibernate.exception.JDBCConnectionException: Unable to acquire JDBC Connection.

So we checked the Database monitoring in Jira Administration
Administration->System->Database monitoring and the max connections shows as 295

We checked this url

Should we increase our pool-max-size from 300 to 350 in dbconfig.xml? will this solve our issue?

Hi @Ramesh


Clearly, the issue appears to be with the DB connections and new connections are unable to establish and would suggest to have a close at the your database logs to see why it might be closing the connection to JIRA.

You can optimize the database connection pool by increasing the Pool size to 350 and restart the JIRA Data Center on all nodes.

You may also try restarting your database server itself to fix any issues with instability.
