What I see is that if on a 2 socket / 4 cores -> 16 threads system I=20=20 do=20a lot in parallel (e.g. updating ports in several jails), then the=20= =20 system=20may get into a state were I can login, but any exit (e.g. from=20= =20 top)=20or logout of shell blocks somewhere. Sometimes it helps to CTRL-C=20= =20 all=20updates to get the system into a good shape again, but most of the=20= =20 times=20it doesn't. On another system at the same rev (333966) with a lot less CPUs (and=20=20 AMD=20instead of Intel), I don't see such a behavior.
