libvirtError: poll on socket failed: Interrupted system call

[jeremy avnet <brainsik+libvirt@xxxxxxxxxxxxx>]

Hello. I just upgraded from libvirt 0.7.0 to 0.7.5 in Ubuntu Lucid and now my application will get into a hung state. I have to kill it at which point I get the following error from the Python bindings:

Traceback (most recent call last):

  File "/usr/local/app/vm.py", line 246, in launch

    vm.create()

  File "/usr/lib/python2.6/dist-packages/libvirt.py", line 300, in create

    if ret == -1: raise libvirtError ('virDomainCreate() failed', dom=self)

libvirtError: poll on socket failed: Interrupted system call

Some searches turned up a patch involving signals sent by ncurses apps resizing, but this is not an ncurses app. It's a daemonized Python Twisted application. Unfortunately, this problem is making it so the application hangs indefinitely until we kill it and start it again.

Any suggestions as to what might be causing this?

Thanks!
