Attempting to push a branch to my central server fails, with the error message "Out of memory loading unknown object". There is about 60GB RAM free on the git server, plus 144GB free swap space so I am skeptical that it is really out of virtual memory. The atlbitbucket java processes have their resource limit on address space set to "unlimited".
Any suggestions on what to check or how to fix this? Are there any git or bitbucket configuration parameters which might cause this out of memory by being too low?

The atlassian-bitbucket.log shows two messages at the point of the failure, one being:
