They're gonna appear after server restart (Had the same issue).

Nope these guns are not lootable in dayz. The normal scoped version of m107 and M4A1 M203 (not silenced) are lootable in dayz. I don't recommend you keep them.

I don't really have any legit log to compare it to but addWeaponCargo is not a server sync command (weapon appears invisible to other players). Also since Map markers are global, and this piece of log clearly states it's only visible for one player (some kind of item location marker script maybe?). I would still look at the logs but sure looks suspicious to me (unless Rocket made some changes to the code in 1.7.1.5 patch). Edit: Other scenarios would be that someone just picked a weapon and stored some items into backpack (tho in this case "addWeaponCargoGlobal" command should appear). Created a marker (but even then "createMarker" command should appear instead of "createMarkerLocal"). The last command seems like a legit DayZ script (you could confirm it with rocket tho). Edit 2: "building_spawnLoot.sqf" is a legit script that is inside dayz_code.pbo. Considering this happened at the same time the "suspicious" script occured i would double check with other parts of the log to look for similarities, as this may be a false alarm.

I've found two heli crashes today. One had loot and zombies. Second one i found driving with my car and that one didn't have loot. So if zombies spawn there will be loot. And also i think the machinegun is locked couse of rockets anti-cheating scripts (so people won't die by accident).
