http://issues.apache.org/bugzilla/show_bug.cgi?id=27751 Segmentation Fault in shmcb_cyclic_cton_memcpy ------- Additional Comments From [EMAIL PROTECTED] 2004-03-23 17:27 ------- Ouch, ok - I have this gloomy sense that I'm about to dive back into apache code ... I notice you're on apache 2.0.48 ... I could try to help track the problem in that version and worry about migrating it (if applicable) to cvs after, but to avoid the potential for logjams with other issues already fixed, are you able to move to 2.0.49, or better still, CVS (head or 2.0.**-stable)? At the least, have you diffed the ssl module source against later releases or CVS to check if any fixes have already been made that might cover this? Whatever you do w.r.t. apache versions - please email me a copy of the first few pages of a *trace* log during startup (this should give me all the shmcb geometry settings), and then the last few pages leading up to your first crash. I noticed from the info you've already provided that you are caching sessions around ~10Kb, which would indicate that you're using client-authentication and probably with some biggish certs (or longish cert-chains). My hunch is that this is triggering some wrap-around issue, either in the cyclic logic itself or in the use of variables of insufficient size. Please mail me the details privately, no point drowning the bugzilla database. As/when I have potential suggestions/fixes, how should we handle that? Can I send you diffs to try? Can I shell to a box where this can be reproduced? Thanks again for the detailed report. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
