Our confluence instant goes down or becomes unavailable around 4PM - 5PM CST

Question

Hi Team,

Our confluence application becomes unavailable (error Service unavailable or error 500).

We have faced the issue multiple time in last week which is impacting the business.

We restarted the confluence service to bring up the application.

We tried to find the root cause but no luck. Please consider the issues as priority and help us to resolve the issue.

We have attached the support log, let us know if you need any more information.

Please contact me @Vinod Honnalli (+91-9844086794) for any clarification.

Thanks in advance.

Hey Vinod!

My first thought, since this occurs around the same time every day, is a backup process that's locking the DB.  I've definitely run into that before.

I did take a quick peek at your logs, and I am seeing quite a few deadlocks:

Also, it looks like you're running this instance on Windows.  Make sure that any anti-virus scanners are set to ignore the directories in this article:

Good luck!

What does your log file say around the time it is becoming unavailable?  What is the server doing at that time?
