hello Roger. I am running the C version of xenstored, the oxenstored file is not installed on my server. With that said, I have figured out that the queue length on the xenstored socket is 2, meaning there can be no more than 3 xl commands runing simultaneously on a given xen installation. I'm guessing, but do not know for sure, that running the oxenstored version of the xenstored daemon wouldn't change this situation since I believe that queue length value is a kernel default. I looked through the sysctl variables, but don't see an obvious variable to change this queue length. The error message I quoted comes from kern/uipc_socket.c, which actually prints the queue length in the message itself. I can learn to live with this limitation, I'm just surprised no one has run into it before, since I'm not running a large server implementation, and I assume there are those who are using this for larger deployments than I am. -thanks -Brian
