Hello, while rsync(1)-ing an 1 GB file the rpi gets almost unresponsible after a while and on the serial console there are lots of smsc0: warning: failed to create new mbuf kernel messages. Occasionaly dotted with the [zone: mbuf_cluster] kern.ipc.nmbclusters limit reached kernel message. The problem is reproduceable. Increasing the value of kern.ipc.nmbclusters by the factor of 2 just delayed the moment the problem happens. An old r254984 kernel does not show this problem. r257114 and r255943 do. A test with r255463 is currently ongoing. Ralf
