I believe this is a good estimation of how it breaks down. > The only way to trigger a segmentation fault was instead to set > Cache-Limit to a ridiculously low value. Perhaps I was lucky. It is difficult to probe deeper with the first bug complicating #474947. Bugs #409336 and #443564 may be similar, or perhaps the exact same issue. > So my conclusion is that the forthcoming release notes do address the > problem some people may encounter in upgrading from Etch to Lenny. > > I propose the attached patch, though, since it is funny to suggest a > value of 12500000 (bytes) when the internal value in Lenny is 20MB. > I hope someone in the d-relase team can apply it.

I must suggest that the release team think very carefully about this. The earliest manifestation of the former (MMap problem without the core dump) is bug #178623. For the past 5 years, every release has had this bug multiple times as an important issue and had to have it documented in release notes. I'm estimating 25-50 reports, plus a large number of people who found the workaround via Google or simply looking at the reports and decided that since it was reported and a workaround was known, a fix must be under way. This effects a rather large number of people. Given past history, no matter how high the limit (workaround) is set now, a significant number of people will encounter it within the lifespan of Lenny. Worse, when the next version beyond Lenny is produced, upgrades will very likely trigger this bug yet again and a horde of people will encounter it. I must therefore suggest that at the very least, the first part of this bug is too severe to allow to continue on to yet another release. Despite the pain now, that it is better to solve this issue and avoid yet more pain down the road. -- (\___(\___(\______ --=> 8-) EHM <=-- ______/)___/)___/) \BS ( | [EMAIL PROTECTED] PGP F6B23DE0 | ) / \_CS\ | _____ -O #include <stddisclaimer.h> O- _____ | / _/ 2477\___\_|_/DC21 03A0 5D61 985B <-PGP-> F2BE 6526 ABD2 F6B2\_|_/___/3DE0 -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
