** Description changed: I am using Juju on Power 8 hardware and I get a panic when I use juju to ssh to a system. The reproduction steps are juju init juju bootstrap -e local + juju switch local juju deploy local:trusty/ubuntu juju ssh ubuntu/0 (use the session to the local machine and after some time the panic happens and the screen is unreadable.) ubuntu@ubuntu-local-machine-1:~$ panic: runtime error: invalid memory address or nil pointer dereference [signal 0xb code=0x1 addr=0x8] goroutine 11 [running]: code.google.com_p_go.net_websocket.Send.N40_code. google.com_p_go.net_websocket.Codec /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/webso cket/websocket.go:293 launchpad.net_juju_core_rpc_jsoncodec.Send.N48_launchpad.net_juju_core_rpc_jsonc odec.wsJSONConn /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/conn.go: 21 launchpad.net_juju_core_rpc_jsoncodec.WriteMessage.pN43_launchpad.net_juju_core_rpc_jsoncodec.Codec /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/codec.go:178 launchpad.ne t_juju_core_rpc.send.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launch pad.net/juju-core/rpc/client.go:72 launchpad.net_juju_core_rpc.Go.pN32_launchpad.net_juju_core_rpc.Con n /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/client.go:174 launchpad.net_juju_co re_rpc.Call.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launchpad.net/ juju-core/rpc/client.go:148 launchpad.net_juju_core_state_api.Call.pN39_launchpad.net_juju_core_state_ api.State /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:168 launchpad.net_juju_core_state_api.Ping.pN39_launchpad.net_juju_core_state_api.State /build/buildd/juj u-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:158 launchpad.net_juju_core_state_api .heartbeatMonitor.pN39_launchpad.net_juju_core_state_api.State /build/buildd/juju-core-1.18.1/sr c/launchpad.net/juju-core/state/api/apiclient.go:149 created by launchpad.net_juju_core_state_api.Open /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/state/api/apiclient.go:143 goroutine 1 [syscall]: goroutine in C code; stack unavailable goroutine 3 [syscall]: goroutine in C code; stac k unavailable goroutine 10 [IO wait]: code.google.com_p_go.net_websocket.ReadByte.N57_code.google.com_p _go.net_websocket.hybiFrameReaderFactory /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.n et/websocket/hybi.go:113 code.google.com_p_go.net_websocket.NewFrameReader.N57_code.google.com_p_go.ne t_websocket.hybiFrameReaderFactory /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/webso cket/hybi.go:126 code.google.com_p_go.net_websocket.Receive.N40_code.google.com_p_go.net_websocket.Cod ec /build/buildd/juju-core-1.18.1/src/code.google.com/p/go.net/websocket/websocket.go:314 launchpad.n et_juju_core_rpc_jsoncodec.Receive.N48_launchpad.net_juju_core_rpc_jsoncodec.wsJSONConn /build/bu ildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/jsoncodec/conn.go:25 launchpad.net_juju_core_rpc _jsoncodec.ReadHeader.pN43_launchpad.net_juju_core_rpc_jsoncodec.Codec /build/buildd/juju-core-1 .18.1/src/launchpad.net/juju-core/rpc/jsoncodec/codec.go:113 launchpad.net_juju_core_rpc.loop.pN32_lau nchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-core/rpc/se rver.go:344 launchpad.net_juju_core_rpc.input.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juj u-core-1.18.1/src/launchpad.net/juju-core/rpc/server.go:317 created by launchpad.net_juju_core_rpc.Sta rt.pN32_launchpad.net_juju_core_rpc.Conn /build/buildd/juju-core-1.18.1/src/launchpad.net/juju-cor e/rpc/server.go:200 Here are the specifics on the host system. ubuntu@stilson-01:~$ uname -a Linux stilson-01 3.13.0-32-generic #57-Ubuntu SMP Tue Jul 15 03:50:31 UTC 2014 ppc64le ppc64le ppc64le GN U/Linux ubuntu@stilson-01:~$ dpkg -l | grep juju ii juju 1.18.1-0ubuntu1.1 all next generation service orchestration system ii juju-core 1.18.1-0ubuntu1.1 ppc64el Juju is devops distilled - client ii juju-deployer 0.3.6-0ubuntu2 all Deploy complex stacks of services using Juju ii juju-jitsu 0.20-1 all external tools to enhance juju ii juju-local 1.18.1-0ubuntu1.1 all dependency pack age for the Juju local provider ii juju-mongodb 2.4.9-0ubuntu3 ppc64el MongoDB object/ document-oriented database for Juju ii juju-quickstart 1.4.1+bzr88+ppa25~ubuntu14.04.1 all Easy configurat ion of Juju environments ii python-jujuclient 0.17.5-0ubuntu2 all Python API clie nt for juju ubuntu@stilson-01:~$ getconf PAGE_SIZE 65536 I got this error when testing a fix for another bug: https://bugs.launchpad.net/ubuntu/+source/gccgo-4.9/+bug/1304754 Since the dmesg looks different we believe this is a new problem.
