Large Network Transfers Can Cause a Solaris 10 Virtual Machine's Network Connection to Stop Responding (2176)
When you transmit large amounts of data over the network from a 32-bit Solaris 10 guest, the guest network driver might stop responding in a Queue Full (QFULL) state. This state indicates that one of the internal queues in the driver is not being properly serviced and has filled up. As a result, the guest loses network connectivity, and applications and services (such as NFS, NIS, and DNS) that access the network hang or fail. In addition, commands run in the guest to display information about the network status (such as ping, ifconfig, and netstat) stop responding.Note: The vmxnet driver is not affected by this problem as severely as the default pcn driver is, and thus it is advantageous to install the VMware Tools package on the Solaris 10 virtual machine.
To work around this problem, reboot the guest operating system.
Note: This issue is specific to Solaris 10 guests. It is being tracked by Sun under 6302632.
