Summary
When LFS is enabled for a repository and Automatic branch merging is enabled, plan branches may spend a significant amount of time ~35 minutes to 1 hour in the queue before it starts building a new change.
Environment
This applies to Bamboo DC or server versions.
Diagnosis
- Perform a thread dump
The analysis will show the threads are blocked waiting for a slow-performing LFS thread.

Cause
- It is potentially caused by a performance bottleneck when older Git and LFS versions are installed and used (e.g. Git 1.8.3, LFS 2.10.0).
Solution
- Upgrade Git and LFS to a more recent supported version.
