[spambayes-dev] Socket problem

[Paolo Invernizzi]

Hi all,

I've some problems with the current pop3proxy.py script.
I'm running spambayes CVS on a FreeBSD 5.1 machine, with python 2.2.3

On my machine I'm lunching the pop3proxy.py with cron at startup, and 
I've a fetchmail process that check the pop3proxy every 10 minutes for 
pop3 updates... and all is fine.

But... sometimes during startup, or after a one or two days, the process 
exits with the following error...

Running the pop3proxy, lanched by cron at startup, works fine, but

SpamBayes POP3 Proxy Beta1, version 0.1 (May 2003),
using SpamBayes POP3 Proxy Web Interface Alpha2, version 0.02
and engine SpamBayes Beta1, version 0.1 (May 2003).

Loading database... Done.

     r,w,e = select.select (r,w,e, timeout)
ValueError: filedescriptor out of range in select()


Fredrik Lundh suggested me to use pool, instead of select, so I turned 
asyncore to:
	asyncore.loop(map=context._map, use_poll=1)

Now the error reported is:

Any advice??
I've started a thread on this on c.l.python also
