It is a bug in the latest release of the Realism Mod...a few days ago it happened on my server for 10 minutes...so a few days ago I changed the mod to the earlier version and it has not happened since.
Did you also get the exploding Grenades when you spawn?

I ran into something similar on chthulu's realism server where i would suddenly change from rifle to grenade or my mp40 would start shooting, but it was accompanied by frame disruption, etc and the server was over full (as he clearly had problems once the 25th person arrives, even though it is set for 32)
So I just assumed it was a lag thing and the server was about to crash, as it often does.
