On the Linux box, all fresh compilations aside from the sasl 2.1.15 binaries: imapd 2.3.7 + sasl 2.1.15: works imapd 2.3.7 + sasl 2.1.22: works imapd 2.3.9 + sasl 2.1.15: not tried imapd 2.3.9 + sasl 2.1.22: works imapd 2.3.10 + sasl 2.1.15: fails (cannot examine mailboxes, then coredumps prior to calling accept for second connection) imapd 2.3.10 + sasl 2.1.22: fails (SIGSEGV immediately after authentication) I've compiled 2.3.10 both -O2 and with optimisation turned off, to no effect. This is God's way of telling me to move onto a newer OS platform, I think. I'll stick at 2.3.9 + 2.1.22, since it appears to work and it's obviously a better proposition that the 2.3.7+2.1.15 I was running previously. It seems clear the problem has come in with 2.3.10, and as the platform is horrid I'll stop investigating further. In the mean time, is there any way I can run replication from a master running 2.3.9 into a replica running 2.3.10? Or should I back the replica out to 2.3.9 as well? ian ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
