Hi, thanks for the replies, I was very busy and lost the focus on this issue.
However, the last weeks the temperatures were lower and the problem did not show up again. So I think the problem was triggered by the high temperatures, and my cooling (still) seems to be inadequate. Sorry for answering so late. But thanks for the pointers, I did not know about kern.ipc.nmbjumbo9 and its connection to the NIC jumbo frames, will have a look. Kind regards Johannes 2011/10/2 Andrey Zonov <and...@zonov.org>: > Hi, > > I see that you use MTU 9000, have you tried to increase kern.ipc.nmbjumbo9? > Can you also show output of `vmstat -z | grep mbuf'? > > -- > Andrey Zonov > > > 16.08.2011 0:10, Johannes пишет: >> >> Hi, >> >> I use an Intel dual nic for my home server.
