> When a QJM crashes, the in-progress edit log file at that time remains in the
> file system. When the node comes back, it will accept new edit logs and those
> stale in-progress files are never cleaned up. QJM treats them as regular
> in-progress edit log files and tries to finalize them, which potentially
> causes high memory usage. This JIRA aims to move aside those stale edit log
> files to avoid this scenario.
