CSS and GMOD server problem

Whenever I install counter-strike source alongside my garrys mod server, it forces it into constant restart and the server is never up. If I remove the counter-strike files, it works as normal.

I don’t know why its doing this, any help appreciated

Having the same issue over here. Both on my windows and linux servers.

EDIT: actually the linux server is crashing on player join regardless of CSS content.

Yes, I’ve done -verify_all. Issue still exists.

GDB is giving SIGSEV on 0xb7e22c1e in __memcpy_ssse3_rep () from /usr/lib/libc.so.6
GDB Backtrace

Final Edit:
Fixed it with the rollback to 153.
