I upgraded confluence from 3.5.3 to 4.3.3
After update, I faced with serious performance problem.
All User cant't operate.
My environments are
* MySQL 5.1
* Java 1.7
* Cluster Confluence edition but one server
* DB Access with datasource
Sudenlly, Database connection pool is max. It seem that queries are not slow because there are no slow query log.
I can't find out on condition.
It seem that cache statics in 4.3 are ineffective than 3.5.3.
So, amount of queries are increase.
Anyone faced with same problem?
Please help me!!!
I have had this consistently too since upgrade to 4.3.1. There is a known issue with the mywork (notifications) plugin, which is exacerbated by the calendar plugin if you have a large user base, but I doubt that's your problem.
Anyway, I still have the problem since applying the fix for that. Been with Atlassian support for about 2 weeks :-(
Thank you for your reply.
I would like to know your resolution.
What kind of plugins did you ivalid?
Notifications and Tasks - Common Plugin
Notifications and Tasks - Host Plugin
Notifications and Tasks - Confluence Provider Plugin
I hope your problem will be fixed.
I believe the two things you will need to do here are increase your database connection pool, because the addition of Active Objects means more calls to the database, and increase your Heap memory allocation because you will probably find that Confluence consumes more memory in newer versions due to the new features.
Increase memory: https://confluence.atlassian.com/display/CONFKB/How+to+Fix+Out+of+Memory+Errors+by+Increasing+Available+Memory#HowtoFixOutofMemoryErrorsbyIncreasingAvailableMemory-Step2:IncreaseAvailableMemory
However, I believe that once you have done this then it should resolve your issue.
All the best,
Is there any relevant error message being logged in your <confluence-home>/logs/atlassian-confluence.log?
You can start enabling Safe Mode in Confluence Admin > Plugins to see if there's any third party plugin interference.
I faced with strange situation.
I changed setting of confluence with admin function.
ex) changed security setting , invalid plugin
Sometimes, after that same issues has occured.(increase Database connections)
I wonder if changed setting makes cleare aplication cache or invalid it.
But it is occured without changed setting.
Maybe, some operations makes cache invalid.
It's so, all access execute SQL query not via cache.
It makes DB connection increased suddenly.
Now I found out that all most of caches are expired every hours.
Surely, issue has occured every hours.
