Hi,
I'm running into an error that I'm not sure how to fix and was wondering if anyone might have some insight into what's going wrong.
I have roscore and a few nodes running on one machine. Then on a second machine is a node which interacts with nodes on the first machine through service calls. Everything seems to run fine for a while, then the node on the second machine dies with a message:
Unhandled exception in thread started by <bound method TCPServer.run of <rospy.impl.tcpros_base.TCPServer object at 0x2fee1d0>>
Traceback (most recent call last):
File "/opt/ros/cturtle/ros/core/rospy/src/rospy/impl/tcpros_base.py", line 141, in run
(client_sock, client_addr) = self.server_sock.accept()
File "/usr/lib/python2.6/socket.py", line 197, in accept
sock, addr = self._sock.accept()
socket.error: [Errno 4] Interrupted system call
Additionally, the log for this node includes the following messages:
[INFO] 2011-01-12 10:43:14,691: signal_shutdown [error in XML-RPC server]

Any thoughts on where the problem might lie?
Thanks,
