All versions are stable and working in production. Except 7th version
the servers are loaded (la 0.2 to 3) with http/mysql/mail daemons.
Seems like a bug in python socket usage of freebsd for long time.

[issue6692] asyncore kqueue support

2009-08-12 Thread Andrew Azarov 

New submission from Andrew Azarov :

Is there a possibility of such feature in the future releases of Python?
Currently I see only select and epoll available, but on FreeBSD 7.2 with
a lot of connections asyncore (1600+ active HTTP connections) has
problems (not giving complete response) with epoll (select is
problematic after 250+ connections (not enough descriptors)).
