On my server, after updating f20->f21, shell startup is _extremely_ slow.
Using strace, it appears that the problem is dbus
08:22:57 connect(5, {sa_family=AF_LOCAL,
sun_path="/var/run/dbus/system_bus_socket"}, 33) = 0
...
08:22:57 recvmsg(5, 0x7fff640c3970, MSG_CMSG_CLOEXEC) = -1 EAGAIN (Resource
temporarily unavailable)
08:22:57 poll([{fd=5, events=POLLIN}], 1, 25000) = 1 ([{fd=5, revents=POLLIN}])
08:23:22 recvmsg(5, {msg_name(0)=NULL,
msg_iov(1)=[{"l\3\1\0013\0\0\0\4\0\0\0m\0\0\0\6\1s\0\7\0\0\0:1.1155\0"...,
2048}], msg_controllen=0, msg_flags=MSG_CMSG_CLOEXEC}, MSG_CMSG_CLOEXEC) = 179
08:23:22 write(6, "\1\0\0\0\0\0\0\0", 8) = 8
Notice the 30second wait for a response from dbus?
Also in /var/log/messages, various dbus messages such as:
Dec 30 08:19:32 nbecker7 su: (to root) nbecker on pts/0
Dec 30 08:20:02 nbecker7 dbus[809]: [system] Connection has not authenticated
soon enough, closing it (auth_timeout=30000ms, elapsed: 30004ms)
Any hints?
