Node Version: v4.8.0

Went to import a slack backup into my brand new install of rocket.chat (I made zero changes to the admin section). The server got VERY slow during the import and it took a very long time. I let it run through the weekend. Upon my return this morning I see users / channels and a small sample of the actual messages (about 10%). The imported file was about 15MB.

The server itself is a VPS:

30GB HDD
1 CPU Core
2GB of Memory.

Attached is the log file that seems to stop on 4/22. I rebooted today. Restarted the import and see the same behavior.
