I had to tweak the C header inclusion a bit, so that the winbot could
create binary eggs. There's a 4.0.1 release on pypi now, which has
eggs build for Python 2.6 and 2.7 in 32 and 64 bit variants.

 That branch passes all tests, and should be ready for merging.

Re: [ZODB-Dev] ZeoServer, multiple storages and open file handles

2012-10-21 Thread Tim Godfrey 
Hi Jon

Thanks for your response. Is that something that has been done in a later
version of Zeoserver than mine (ZODB3-3.10.3)?

It this your recommended action for the issue I'm having or are there still
some configuration changes I can make?

Tim

 Hi all

 We have a customer on Plone 4.1 and recently we started to see a great
 increase in the number of open file descriptors the Zeoserver process uses.

 We have a pretty big system distributed over many servers as the Plone
 system gets a lot of requests. Currently we are running a Zeoserver with 30
 storages and have 16 Zope clients that connect to it.

 I've had Zeoserver in debug mode to try and get some more insight into
 the problem and I'm seeing a lot of these errors:

 Exception in thread Thread-575:

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


 if the server_loop function in connection.py was changed to call
 asyncore.poll2 as far as I can tell the descriptor out of range
 should go away as it uses the poll call rather than select.
