I have a problem with file upload. When I upload small file in chat i have an error 500 on bar at top of the window.

Error in log:

It's look like second instance try to read file that first instance didn't finish uploading yet. With larger files (more than 1MB) is everything OK. Also when I'm running one instance of Rocket.Chat file upload work properly.
I have an idea to add a Delay (setTimeout()) in function that is responsible for uploading, but i don't know which one it is.

Start with packages/jalik_ufs.js at the ufsComplete method shown in the stack trace, and reproduce the upload using two Rocket.Chat instances with a small file. Compare the behavior with a single instance and with larger files. Done means small-file uploads succeed across two instances without the ENOENT or FileNotFound errors.
