pcn0 intermittent network connectivity issue
I have a solaris 10 x86 installed on a VMware server. It has been runing well for a couple weeks, but started to have network connectivity issue since last week. The network card seems to be up and down every one minute. So I got connection closed after I sshed to it for about one minute.

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
pcn0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 3
inet 192.168.0.13 netmask ffffff00 broadcast 192.168.0.255
ether 0:c:29:61:b4:19

This is what I see in the log file:
