Error in DeferredResource handler

Every once in awhile I received this large error block. It recovers and continues to work without crashing afterwards, but it is a bit disconcerting:

You are using extended front end? It is "normal" because of changes in P2pool that are not updated in it. 12 lis 2013 19:29 "Philip De Leon" notifications@github.com napisa³(a):

Thanks, yes, I'm using the extended front end. I'll open up an issue on their git-hub repository. Unfortunately they don't seem very active with the last commit from months and months ago.

what can we do to encourage the dev to fix it ? I love the extended front end.

[buzztiaan]

I have fixed these errors in https://github.com/buzztiaan/P2PoolExtendedFrontEnd Enjoy

[jedimstr]

Thanks Buzztiaan... using your fork of the ExtendedFrontEnd now (with some visual tweaks). Any idea why Memory Usage graph doesn't work when running P2Pool on a Mac?

[buzztiaan]

sorry, i dont have a mac :)

[j0nny55555]

Would you know how to limit connecting wallet addresses and how to block one permanently? We have someone we a suspecting to be running a botnet mining against us. Also, it appeared as if someone was using out p2pool as a reflection ddos attack. Are there further python hardening techniques?
