Confluence stucks while install or upgrade addons

michael.klinger

We are running several confluence intsances in each instance we got the same problem.

I have got several error Messages in each confluence log while i am trying to install or update any addon. I have already successfully installed some addons and it worked fine until now.

I have tried to clean the plugin cache with no success.

I have taken some scrrenshots from the confluence log file below. Maybe you got a hint for me to solve this problem. Kind regards and thank you

And it stucks like this :

Hello Michael and welcome to the Community!

Thank you for providing the steps you’ve taken this far along with the log output, this helps to understand what is happening with your instance. From the logs, I can see there is an issue with the database connection itself which is causing your problems. Depending on how you’ve configured your database connection, I would advise reviewing your available JDBC connections to ensure you’re not reaching the configured limits. There is an article which discusses your issue at Unable to start due to net.sf.hibernate.exception.GenericJDBCException Cannot open connection and there is an article on how to address your connection pool at Confluence slows and times out during periods of high load due to database connection pool.

Please review the above articles for your issues and let us know if you’re able to make progress.

Regards,

Thanks for your fast reply Stephen .

So i have checked both articles and i have tried both ways with no success. I have checked my postgres database as well. So all tables are available (for examples confluence user, spaces ....) so there should be a database connection. The database interuption only appears if i try to install a new plugin and i need to restart confluence. The strange think is i have allready installed and bought several addons and it worked fine until now. If i restart confluence and i enter the postgres container i see all tables but no plugintable but there should be one i guess ? .

Strangely if i try to install a new plugin the plugintable appears and i got some error message from the container like the picture below. Maybe there is a porblem with the Universal Plugin Manager ? We are running confluence 6.13.4 and now the Universal plugin Manager version 3.0.3. I have seen the license in confluence.cfg.xml is different to the license in the shared home folder but porbably thats not the problem.

Thank you

-The first picture below appears when i am trying to enter the plugindata table in postgres container

Hello Michael,

To understand a bit more, we want to know what is within your configuration files for your database connection. This will help us to understand what is configured along with helping to recreate the issue.

Please let us know what you have set for the following lines within your confluence.cfg.xml file:

<property name="hibernate.c3p0.max_size">

Please let us know what your max threads are also set to within your server.xml file:

maxThreads=" "

This will help to understand your current configuration and to understand what can be adjusted within tested to recreate the issue.
