I started ur script. I'm not sure what it'll show but it's running and I'm monitoring it. :) I added a printlock and made the processResults() just print a status message. There is one problem with ur code, the second SNMP call will never be made. Nonblocking calls always return true. That would be a big problem in production code since we don't know which one we need ahead of time. I would have to spin the dispatcher, see if the oids were defined, and then spin it again possibly. The other major problem with the spin dispatcher method is that I don't know what IP's to poll ahead of time. That's one of the reasons I did it as stand alone threads with blocking SNMP. I wouldn't be able to queue up tons of SNMP calls and then spin the dispatcher and wait for the data. I'ld have to queue up small bits of calls and spin the thing over and over again. So it doesn't really buy me anything. :)

Ok the script completed. It only used about 300 MB of memory. As I expected the non CIDR devices returned nothing. :) I'ld be interested to see how the nonblocking calls behave within worker threads.. Hmm.

Another thing I tried. In my leaker3 I moved the require Net::SNMP down into the entrypoint as eval "require Net::SNMP"; figuring that way there would be *no* objects to clone since the entire module wasn't instantiated yet. Doing that used up even more memory than require'ing it at the top of the script. :P
