I think it would be helpful if you could confirm that it was the apache upgrade (as opposed to some other library upgrade that you did in the meantime or something else entirely). Can you get the 2.2.8-3 packages from snapshot.debian.net, downgrade and check that this fixes the problem? Thanks. Cheers, Stefan Sorry for the delay, but I rolled back, the bug went away, and then I got distracted. So yes, the bug did not exhibit itself seemingly at all on 2.2.8-3. Hopefully that helps. --nwf; pgpWSnyH6p503.pgp Description: PGP signature

It's possible that the crash is related to FORTIFY_SOURCE being used for compiling apache. Did you experience the crash with 2.2.8-3 (which was compiled without FORTIFY_SOURCE), too? How often does it crash, on every connection or less frequently? Cheers, Stefan -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

No, 2.2.8-3 did not have this problem (at least, to judge from my log files). It isn't crashing at every connection, no, as I can still use the site Apache is hosting if I make enough attempts... sometimes works fine for a long time, sometimes takes many connections before one works. Sorry I can't be more exact. --nwf; pgppZZdCggtws.pgp Description: PGP signature
