Or if you really can't: post it here on the dev list. I cannot afford to waste time investigating what may well have been fixed in my working tree. I rather spent it on useful stuff, like buffered reads. For me, getting regression reports about my .eu branch here on the list is much less cumbersome. I'd also rather not pollute the tracker with transient bugs in a moving target. Always inbetween changes, and prior to releases as well, of course I try to do all kinds of unit, profile, stress and regression-testing. But I'm just one person doing this after hours; so I'm not doing it before every single git-push. Simple tests like you did should of course never fail, so I do appreciate 'bt full' backtraces of crashes if you think I may have missed something. Things will start breaking differently again soon, after I push out the buffered read changes. That will be a quite invasive change in several critical parts of the code. But lmtp performance should improve drastically - as far as cpu load is concerned. Until that change is done and I've finished my own testing, the .eu branch will be silent. until later, -- Paul Stevens paul at nfg.nl NET FACILITIES GROUP GPG/PGP: 1024D/11F8CD31 The Netherlandshttp://www.nfg.nl ___ Dbmail-dev mailing list Dbmail-dev@dbmail.org http://twister.fastxs.net/mailman/listinfo/dbmail-dev
