Cannot install Confluence add on "Creately"

Dear Atlassian Support Team,

today, I wanted to install the Creately Plugin for Confluence, for the reason of testing it. Unfortunately the installation process could not finish correctly and I got the following message: An unexpected error occurred. Please refer to the logs for more information.

If I view the logs, they tell me only: Failed to install plugin plugin.8080088289350733754.CreatelyForConfluence_1_8_1.jar

So I thought of looking into the log file and there I see:

2013-01-14 10:15:38,935 ERROR pool-4-thread-3 sf.hibernate.util.JDBCExceptionReporter logExceptions Packet for query is too large (18209280 > 16777216). You can change this value on the server by setting the max_allowed_packet' variable.

java.lang.RuntimeException: There was a problem evicting or flushing a PluginData object

The error log continues... I will attach the log file to this issue.

So I guess there is a problem with the database. But is there anything how I can solve it?

Thanks in advance and kind regards

Benjamin

Hi Benjamin,

I believe the reason you are experiencing this issue is because your MySQL database is not currently configured to allow files the size of the Creately plugin to be uploaded, and this is why Confluence won't let you install the plugin. You can resolve this issue by following the instructions in this document, (which is for JIRA but the same instructions apply for Confluence): https://confluence.atlassian.com/display/JIRAKB/Exceeds+Max+Allowed+Packet+for+MySQL

Once you have increased the max_allowed_packet variable as described in the above linked document then this issue should be resolved.

All the best,
John
