bitbucket OOM java heap space

[Barak Nisim Sonino]

In production, Twice in the last week, we got OOM.

What is the default memory size that bitbucket start? We are using version 8.19

How to increase it?

In the Atlassian docs, we found the following link:

Memory 

Specific: 
"Bitbucket Data Center has been designed to have fairly stable memory usage. Pages that could show large amounts of data (e.g. viewing the source of a multi-megabyte file) perform incremental loading or have hard limits in place to prevent Bitbucket Data Center from holding on to large amounts of memory at any time. In general, the default memory settings (-Xmx1g) should be sufficient to run Bitbucket Data Center. Installing third-party apps may increase the system's memory usage. The maximum amount of memory available to Bitbucket Data Center can be configured in _start-webapp.sh."
