BUG: Memory Leak Causes Kernel Panic on Linux (Ubuntu)

[cometdripper88]

Describe the bug
I have pretty much confirmed that the InertiaAntiCheat mod creates some kind of memory leak on my linux box because I cannot replicate this issue without the mod installed.

Basically, with this mod installed, when enough players join the server and go through validation, the memory taken up by the server will permanently increase. When enough players join and get validated, eventually the server runs out of memory causing a kernel panic.

To Reproduce
Steps to reproduce the problem:

1. Install Ubuntu (or any Linux Distro, it should be mostly the same)
2. Set up Inertia on the server (with the linux distro) and the client
3. Watch as memory goes up ~100M/sec while Inertia does validation. Depending on how long the validation takes, this can add anywhere from ~100M of memory to several Gigabytes. This memory does not go down and eventually, when enough players get validated, there is not enough memory for the server to handle and a kernel panic happens (forcing phyiscal presence to shutdown because ssh isn't accessible).

Expected behavior
Watch as your linux box slowly moves toward imminent shutdown, and eventually, death.

I tried to lower the maximum memory in the startup flags, and somehow the java process exceeds that memory, and still causes my linux box to run out of memory...

EDIT: I should also note that the modpack size is quite large (155 MB) which may be significantly affecting this issue.

EDIT2: I have changed the transfer mode to "id" instead of "data" and this seems to pretty much solve the issue. However, it would be really nice to use the "data" mode because many of my players have already bypassed the "id" mode!
