Interesting that it's "acl_users/manage_edit" that's causing them. This might be something for the Collector...
hm... yes, in this particular case it is a combination of DCO2 weirdness and XUF weirdness, though I'd lay most of the blame on DCO2... there is something weird going on with transcations and DCO2, but I don't have the skills enough to pinpoint the exakt problem and report it to MattK. This is not the only place we've had these problems... I know that Steve Alexander has done some work on improving the transaction mecahnism in Zope, but I don't know if it'll find it's way in the Zope core... Still, would e mice to know how they occur.... will search the archives as you suggested. Re: asyncore problems, these are old problems (did a searchon the web), no solution so far... /dario
