Gmod Error that is crashing the server.

Hello, my name is Jon Elam. My TTT server is currently crashing a lot more than usual. From what I’ve seen, It’s caused by this error:

00:20:55 Engine error: player\guerilla.mdl (2) at -1. -1. -1. in contact with player\guerilla.mdl (2) at -1. -1. -1., crash. dist = -1, minq = 99999999999999998000000000000000000000000000000000000000000000000000000000000000000

Does anyone have any idea how to fix this? I honestly have no idea what’s happening. If anyone has a solve to this then please, By all means, tell me and future users.
