High memory usage crashs machine on Linux

Hi, I have a small business license and use MongoBooster in 4 desktops.

In all of them we have a problem that happens from time to time, it's about memory usage.

MongoBooster just start to use all available memory, even swap memory, until the computer crashes.

If we leave MongoBooster open for a couple of hours, even without using it, it's high probable that the problem will happen.

The only way to avoid the computer crash is killing the mongobooster process as soon as we perceive that memory usage is starting to grow, it's possible to see the memory consumption with the top command, and if the user is fast enough, it's possible to avoid the crash.

All our computers uses Linux Ubuntu 16.4 LTS, we use the AppImage package, it's happening since we start using MongoBooster, my computer has the versions downloaded 4.0.1, 4.0.2, 4.1.3, 4.2.0, all of them crashes from time to time.

We all use our connections over a SSH tunnel.

One way to force the problem is make a connection, do some queries, suspend the machine, recover the machine, the system will take some seconds to reconnect on the Wifi, this is a very probable way to make the problem appears.

Other way is to connect Mongobooster, run some queries, leave the computer alone so the screensaver will be displayed, wait about 1 hour, come back, high probable that the machine will be crashed.
