Bitbucket server is too slow

[SeongUk Cho]

I installed bitbucket server on 4Core(Intel Xeon E5-2690v3), 10GB RAM server machine with ubuntu 18.04.

And I put bitbucket server behind the HAProxy.

But bitbucket server is very slow. I don't know any reason that slowdown bitbucket server.

The only way to make it normal even temporary is restarting the atlbitbucket service.

After I restart the bitbucket service, it works fine for a few moments but some point server slowdowns again. 

I can't find or fix this problem so I need some help.

Hi,

There will be multiple reasons for this.

Ways to analyze:

1.Check application logs for any error message.

2.Check GC logs .

3.Analyze thread dumps taken during slowness.

There seems no error message in bitbucket log.

But this log was found:
