An HP OpenView instructor mentioned many network devices' SNMP agents have
a nasty behavior, which has been termed "spinning the agent", if too many
SNMP requests are received.  Basically the agent crashes -- possibly
bringing the functioning device down with it.  

He then stated that IOS's response to a "spun agent" was an impromptu
'reload'.  (I know, more rumor mongering, but I am interested to know if
anyone else has seen this.)
