Hi,

One of our RMI call is often hanging at java.net.SocketInputStream.socketRead0, the thread stack looks like,

"RMI TCP Connection(8539)-10.179.38.14" daemon prio=3 tid=0x01d29c00 nid=0x22193 runnable [0xc486e000]

The issue is not 100% reproducible and I have ever googled the issue from Internet and found that somebody said that the heavy system or networking instability will result in the issue...

I checked the system status when the issue was happending and we still had 3-4G memory left and the free CPU was about 50%.

Could you please tell me why we will have the problem and how can I solve it?

Thanks
