Memory leak on specific new worlds

One of the worlds I generated used the server software would cause memory leak issues on linux. It would use more memory than allocated and invoked watchdog to shut down the server the first time and caused a system-wide freeze the second time. It only happened on this specific world so far that was not logged onto by a user until the second time.I've attached the world, crash report, and anything else I found that may be relevant.

The startup flags were: -jar -Xms2650M -Xmx3G

The crash report shows memory usage of 4822 MB
