I've just had a sending window hang for over 3 hours without progress
(I left it that long to see what happened). The rest of the interface
appears to be working, but the send cannot even be cancelled.
On killing and restarting Evo, I was asked if I wanted to recover the
pending message. I did so and resent it. The send completed
immediately. I've added a backtrace to the above BT report. I also
tried strace on the hung instance:
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN},
{fd=11, events=POLLIN}, {fd=36, events=POLLIN}], 5, 99) = 0 (Timeout)
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN},
{fd=11, events=POLLIN}, {fd=36, events=POLLIN}], 5, 0) = 0 (Timeout)
poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}])
writev(3, [{iov_base="\22\0\16\0Z\350\347\4\311\1\0\0\6\0\0\0
\0\0\0\10\0\0\0\7\0\0\0\0\0\0\0"..., iov_len=408}, {iov_base=NULL, iov_len=0},
{iov_base="", iov_len=0}], 3) = 408
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN},
{fd=11, events=POLLIN}, {fd=36, events=POLLIN}], 5, 100) = 1 ([{fd=3,
revents=POLLIN}])
recvmsg(3, {msg_name=NULL, msg_namelen=0,
msg_iov=[{iov_base="\34\0\276\226Z\350\347\4\311\1\0\0\2\237\300\2\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0",
iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
recvmsg(3, {msg_name=NULL, msg_namelen=0,
msg_iov=[{iov_base="A\0\305\226&\267\371\4\3\0\202\0\252\336\341\4\0P9\0\0\0\0\0\0\0\0\0\0\0\0\0",
iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0}, 0) = 32
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN},
{fd=11, events=POLLIN}, {fd=36, events=POLLIN}], 5, 99) = 0 (Timeout)
recvmsg(3, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily
unavailable)
poll([{fd=3, events=POLLIN}, {fd=4, events=POLLIN}, {fd=5, events=POLLIN},
{fd=11, events=POLLIN}, {fd=36, events=POLLIN}], 5, 0) = 0 (Timeout)
poll([{fd=3, events=POLLIN|POLLOUT}], 1, -1) = 1 ([{fd=3, revents=POLLOUT}])
etc. etc.
This kept going the entire time until I killed Evo.
