gmod dedicated server doesn't work properly on linux

I’d installed srcds for linux on CentOS 6 x64 using this manual:
srcds starting successfully, but when i spawn TDM Car - i get error in console and can’t use the car and car is not colliding with everything.

Tried to use invalid object (type IPhysicsObject) (Object was NULL or not of the right type)

if I spawn 2 cars - server is crashing.
When i spawn default jeep - there is no bugs and errors in the log.

I find that IPhysicsObject - is a part of, but this lib is exists. and “ldd” shows that all dependencies are exist.

also i see error like “zlib_64 not found”, but Package zlib-1.2.3-27.el6.x86_64 already installed

i’m trying to use:

./steam -command update -game tf -dir . -verify_all
./steam -command update -game garrysmod -dir . -verify_all

bit no success

help me please :frowning:
