Hi,

we have a very strange problem, which only occurs on the production system. Test environment is okay not working too. 

It is not possible for administrators to manually upload plugins, an error occurs and the following exception is logged:

2014-09-15 10:43:59,837 WARN [com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#1] [mchange.v2.resourcepool.BasicResourcePool] run Failed to destroy resource: com.mchange.v2.c3p0.impl.NewPooledConnection@5a29db1c

Some information:

  • Confluence is 5.4
  • Normal usage is working fine
  • The system is not allowed to access the internet and though not the marketplace

Any ideas?

Thanks, Adrian

Hi Adrian, it's a bit difficult to determine the cause of this issue, but it looks like something related to database communication because of the message "Communications link failure".

Here some of the things that you may to check:

  1. Update Universal Plugin Manager to the latest compatible version;
  2. Check your database server settings, specially max_allowed_packet and transaction-isolation (it must be READ-COMMITTED)
  3. Configure a validation query SQL, so that the application will validate if the connection pool isn't broken.

I hope it helps.

Cheers

There is a JIRA KB for the same error. Maybe try the same?

If that doesn't work, try this: https://confluence.atlassian.com/display/CONFKB/%27Communications+link+failure%27+CommunicationsException+Error+with+JIRA+User+Management+on+MySQL
