Hi, I've been running squeeze-lts VM on a squeeze-lts Xen server.
Updated the VM to wheezy and it mostly works okay, but but mail connections fail with a segfault. # swaks -4 -s mail.affinityvision.com.au -tlsc -p 465 --ehlo affintiyvision.com.au -au andrewm -ap -t [email protected] -f [email protected] Password: ********************** === Trying mail.affinityvision.com.au:465... === Connected to mail.affinityvision.com.au. Segmentation fault If I connect to a different machine running (even from the /faulty/ VM), it works fine.

NB: A simpler VM on the same Xen server has been running Wheezy for quite a while, but it isn't a mail server. Any ideas, futher tests? Thanks AndrewM
