I'm not a network guru ... but, back in 2005, James Hofmeister wrote:

"Re: Inbound buf pool overflow on mpeix 7.0
Cases where the inbound buffer pool runs out is typically a result of a socket application which is receiving data from a peer and is not performing recv. The easiest method to trouble shoot this type of a problem is to run nettool;info="res;di;quit" and then terminate one socket application, then re-run nettool;info="res;di;quit" and monitor for a drop in buffer utilization. When you see a drop in the buffer utilization, you have identified the wayward application.

Causing system to be un-accessible. We could still access the system via the console and shutdown the network and restarted. All looks fine for a while then later see it rising again.
