One of my plugins causes the problem above but can' t share them because of privacy reasons. I think the startup command may cause this problem:
Code:
./hlds_run -console -game [hidden] -port 27021 -sport 26900 +map de_dust2 +maxplayers 21 -pingboost 0 -strictportbind -norestart -debug -condebug -noipx +sv_lan 0 -nojoy -insecure
Plugins used to work without problems in my previous windows server
