hi! i was wrong with the patch. we deactivated the self.close() in line 320 :-) cheers, lars
today we found a critical bug in zope and we would like to know wether anyone knows a solution.
it seems that zope crashes under heavy load (which means more than 15 hits/sec) and beeing authenticated against the zope server.
try for example the following:
authenticate against your zope server, e.g http://some.server.com/manage. afterwards view a page on this server with some dtml code. now reload this page very fast and very often by pressing F5 permanently. after a little while (between 30 seconds and 2 minutes) the connect may fail. on the server side we saw for example the following message:
2000-02-11T16:07:06 ERROR(200) ZServer uncaptured python exception, closing channel <zhttp_server listening :8080 at 860d2d8> (exceptions.TypeError:unpack non-sequence [/opt/shares/volume2/zope/Zope-2.1.4-src/ZServer/medusa/asyncore.p y|poll|59] [/opt/shares/volume2/zope/Zope-2.1.4-src/ZServer/medusa/asyncore.p y|handle_r ead_event|285] [/opt/shares/volume2/zope/Zope-2.1.4-src/ZServer/medusa/http_serve r.py|handl e_accept|609])
we tried to connect from another maschine and successed. but the maschine who failed before is in most cases not able to reconnect for a longer time.
we were able to reproduce this behavior many times with IE 5.0.
our python developer added the code self.close() to ZServer/medusa/asyncore.py at line 320 where self.close() is:
def close (self): self.del_channel() self.socket.close()
afterwards the zserver seems to work stable. we have to test out a bit more.
cheers, lars
