I am experiencing two network related issues with the computer. First issue ----------- When compiling lang/ruby19 the network freezes. The build was done directly from the command line using ssh. After a while ssh reports "Write failed: Broken pipe". I attached the monitor and no messages were displayed on the output (and the machine was still running). The Intense-PC does not respond to pings at this point either. Of note, I was capable of transferring multiple GB of data and successfully compiled other ports but compiling lang/ruby19 messes up everything. Second issue ------------ After a period of uptime (after the freeze from building lang/ruby19) the entire network stops working, nothing is capable of connecting or communicating on the network. When I do a tcpdump (from a different, affected computer) I find the following: 20:57:58.254626 MPCP, Opcode Pause, length 46 These messages get repeated a few times a second. The moment I disconnect the Intense-PC from the network functionality is restored (and is clearly illustrated by the tcpdump). Information ----------- # uname -a FreeBSD dragonbsd 10.0-RELEASE FreeBSD 10.0-RELEASE #0 d44ce30(releng/10.0): Sun Feb 9 20:11:55 SAST 2014 root@dragon.dg:/tmp/home/freebsd/10.0/src/sys/MODULAR amd64 # ifconfig lo0: flags=8049 metric 0 mtu 16384 options=600003 inet6 ::1 prefixlen 128 inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 inet 127.0.0.1 netmask 0xff000000 nd6 options=21 em0: flags=8843 metric 0 mtu 1500 options=4219b ether XX:XX:XX:XX:XX:XX inet 192.168.0.160 netmask 0xffffff00 broadcast 192.168.0.255 nd6 options=29 media: Ethernet autoselect (100baseTX ) status: active re0: flags=8843 metric 0 mtu 1500 options=8209b ether XX:XX:XX:XX:XX:XX nd6 options=29 media: Ethernet autoselect (none) status: no carrier Any assistance to resolve this issue will be greatly appreciated.
