I'm trying to write some informations from linux-2.6-xen-sparse/drivers/xen/netfront/netfront.c like the number of packets sent, received and dropped  to the Xenstore. I succeed to get the information written correctly for several second and than i got a crash of the virtual machine which had executed the instruction of writing.

For example:

  I  put this instruction ligne after updating the number of packets transmitted in netif_poll() function of the code

 np->stats.rx_packets++;  // rx packet update
 err = xenbus_printf(XBT_NIL,np->xbdev->nodename,"netfront_packet_rx","%lu ",np->stats.rx_packets); // the information is correctly written  before the crash of the virtual machine

thank for your help and recommendations
