Re: Migration from cyrus 3.4.3 to 3.6.0~beta2-1 failed, mail fixed

FWIW, we were able to reconstruct the [email protected] mailbox and 
others and they seem to be working fine now.

sudo -u cyrus /usr/lib/cyrus/bin/reconstruct -rfG 
user/[email protected]

I assume the segfaults (example log entries from 3 servers below) caused 
cyrus to leave the mailbox in a "messed up" state and reconstruct fixed 
it.  Yay for reconstruct!

isabella kernel: [18089238.548452] ctl_cyrusdb[13579]: segfault at 0 ip 
00007f355044be4f sp 00007ffd59d93aa8 error 4 in

nerissa kernel: [18778057.193717] ctl_cyrusdb[5257]: segfault at 0 ip

We love Cyrus. Thanks to everyone that keeps it going.
