(bc_state = =3D 0x00004006) Running with simple jail's on it, the server runs flawlessly until = reboot =85 but as soon as I start running Virtualbox on it, I get = sporadic server 'hangs' =85 never the same time, usually can be = triggered by heavier then normal load on the virtual box (ie. running an = rsync session from the base server into the vbox environment) =85=20 When it happens, I can *usually* connect via the DRAC / remote console = and login =85 but doing an 'ifconfig down' on the device and then back = up makes no difference =85 if I send a ctl-alt-del through the remote = console, more often then not, it will free up whatever is going on, so = that pinging works again, but, of course, I've already hit ctl-alt-del, = so its rebooting even though now I don't need it to =85 Based on a page on the wiki about tuning for vbox, I have set: net.graph.maxdata=3D65536 but I've seen this happen even with that set, so not sure if I'm just = still triggering it, or its something else I'm experiencing =85 So, two questions: 1. is there something I can run to see if I *am* in fact hitting that = limit? =20 2. is there something I can do, like ctl-alt-del, but without the = reboot, to 'free' the ethernet?
