And here's another crash trace probably related: #0 0xf5c3785e in VectorTransform () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #1 0xf5c388bf in TransformAABB () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #2 0xf5ba1e1e in CTFProjectile_Arrow::PositionArrowOnBone () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #3 0xf5ba33e2 in CTFProjectile_Arrow::StrikeTarget () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #4 0xf5ba2c0b in CTFProjectile_Arrow::ArrowTouch () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #5 0xf5533062 in CBaseEntity::Touch () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #6 0xf576f8be in CBaseEntity::PhysicsStartTouch () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #7 0xf577180f in CBaseEntity::PhysicsMarkEntityAsTouched () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #8 0xf5771b7a in CBaseEntity::PhysicsMarkEntitiesAsTouching () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #9 0xf5771be4 in CBaseEntity::PhysicsImpact () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so #10 0xf576929e in CBaseEntity::PhysicsPushEntity () from /home/srcds/tf2server/orangebox/tf/bin/server_i486.so
Maybe somehow some variables (origin, angles, etc.) are getting set to invalid/NaN values which is messing with these functions? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Tony Paloma Sent: Sunday, July 19, 2009 6:33 PM To: 'Half-Life dedicated Win32 server mailing list' Cc: 'Eric Smith' Subject: [hlds] ClipRayToVPhysics crash and other related crash Lately, I've been getting crashes in the ClipRayToVPhysics function and other physics related functions. It's been occurring on more than one server and seems to happen more often recently. The increasing frequency leads me to believe that it could be some kind of exploit. I do not run SourceMod.
