What steps will reproduce the problem?
1. stuff a lot with the bot, like listen an irc channel
2. do ector.write()

What is the expected output? What do you see instead?

self.memoize(obj)
RuntimeError: maximum recursion depth exceeded

What version of pyECTOR are you using?

0.4 Released

What version of Python are you using ?
On what operating system?

2.5 on debian lenny

Please provide any additional information below.

Good bot in fact, but this is big problem if it s impossible to save brain
to disk :/

That's true, I did not elaborate a lot on save.
Can you send the log file?

As the model of ECTOR is a network, there are many circular references, and I 
think
the maximum recursion depth is exceeded (what? that's what the error message 
says? true).

Now, I have to look for a solution...
As I have not explored this way, that article is a good beginning to me:

In the sys module, there are the methods getrecursionlimit and setrecursionlimit

On my system (Acer Aspire 5520)
sys.getrecursionlimit()
returns 1000

I managed to sys.setrecursionlimit(200000000), but even with this setting, 
pickle
eventually crashed. 

A solution to this might be to implement a custom save/load, instead of using 
pickle.
I will try and see if I can help with this.

Also, great program and concept.

use cPickle as pickle

This line fixed my @write problems, seems to handle circular refs much better.
